I’m bad at math. I really am. So there. 
I’m quite bad at creative work that you do with your hands. I can’t draw, paint, sculpt, or work with clay. I can sing and play music, but I don’t understand theory all that well, so I’m not a good songwriter or composer. I think it’s related to my being bad at math (see? It IS relevant!), since a lot of that seems to use the same sort of skills.
Also? I can’t fold linens to save my life.
I have an embarrassingly bad sense of direction. It’s probably the #1 thing about myself that I’m most ashamed of.
If I’m in familiar territory (like my tiny hometown), I’m fine. If I’ve been somewhere a few times, I’m (usually) fine - provided I can go the same route I’m used to going to get there. If I have to make any kind of change (like having to take a detour), forget it.
If I’m in an area that I’m not familiar with, I will get lost. It’s a given. I will get lost even if I have a map and yes, I’ve even gotten lost with a damn GPS system in my car. It rattles me every time and I get shaky and sometimes even cry. There have been times I’ve simply given up and gone home (once I could find my way back home) rather than go to where I was heading. Cary, NC (almost always on those “America’s Best Cities Evar” lists) puts me in tears EVERY SINGLE TIME I go … a very pretty town that I’ve grown to despise simply because I’m incapable of navigating it.
Other than this, I’m a reasonably intelligent person. I’m no genius, but I’m certainly not stupid so I’m completely baffled (and embarrassed - did I mention embarrassed?) by my terrible sense of direction 
I have a really, really tough time remembering people’s names. This isn’t getting any better as I get older. I’m very good with faces, though.
I can’t roll my tongue and pretty much everyone else in my family can. I feel cheated.
I have dyscalculia (or whatever it’s called) where numbers jump around on me, although I’m not bad at math at all. Just need to be extra careful and recheck things a lot.
I have trouble truly multi-tasking. I can do single tasks in a serial manner, but if one task is ultra important there’s a good chance that one or more of the other tasks will be forgotten.
I’m not good at doing the mundane, boring crap that can be required to get a job done. I suck at the boring details.
I’m not good at music in terms of being able to know notes and things like that, although it’s not clear if that’s lack of talent or lack of training.
Not good at picking up on subtle hints. Bludgeon me with a mallet if you want to be sure you have my attention.
Don’t tolerate bureaucrats well at all. I got us “fired” from our doctor recently for making a snide remark when they wouldn’t see my daughter until they had our updated insurance information.
Please note Rule 1 in the OP.
When I watch a movie, I easily get the actors confused and can’t seem to follow the plot. I’m always asking, “Who’s he, again? And why are they doing that?" I feel like I’m the only one who has this affliction.
I’m an engineer, and pretty good at math. I also teach algebra as an adjunct professor at a local college.
But I can’t do any math in my head; I need to write it down. When doing very simple arithmetic (e.g. 7+4), I will use my fingers to count.
I am bad at dating, but not for this reason. I’m actually a very interesting and very social person and could very well get dates if I wasn’t such a wuss. I’m really afraid of rejection and don’t dare show interest because, well, rejection is usually what happens when you show interest. But not always, and I know I’d get a positive result if I only tried.
I’m also lazy. I’m pretty good at my job, but the reason why I’m not further done with my Ph.D. thesis is that I find it hard to psych myself to do things that are unpleasant or things that I don’t want to do right now. It’s hard for me to self-discipline, I need outside discipline. I very well might have finished by now if I’d been able to motivate myself better.
Actually, it seems that most of the stuff I describe here is linked to the fact that I have trouble doing stuff that is scary/unpleasant, either because I can’t motivate myself or because I’m afraid of other people’s reactions. And I’m often scared of stuff, even stuff that most people aren’t afraid of. Here’s an anecdote: I was in Poland the last few weeks, and I wanted to mail postcards to some people. It took me two days before deciding to enter the post office (and I had to have people come with me) because even though it’s kind of obvious what I want to do when I bring postcards to the post office, I was afraid of not being able to express myself since I only speak a few words of Polish, and of pissing people off. In a sense, this is the main problem of my whole life, and it is definitely something I’m not good at.
I have this to a lesser degree. Sometimes I confuse the actors, but most of the time not. Other than for a few actors, I usually can’t find their names though. (That’s probably just due to unfamiliarity with them.)
I have a terrible sense of direction. Really, just awful. Whenever I’m lost, I ask my gut which way it thinks I should go – and then go in the opposite direction of that. I discovered GPS two years ago, and it changed my life.
I’m an awful runner. I love running, but I’m very slow–when I first started, I was ‘‘running’’ 18 minute miles, now I’m down to, say 14-15 minute miles. My best time ever was a 12 minute mile. I used to think it was the fact that I was a Clydesdale (race category for heavier/overweight runners) but now that I’ve lost the weight I’m still a crap runner. Oh well, it’s fun!
No, you’re not the only one. Hell, I’m almost done with a two season show and I still get the names of two of the actors confused…and not only that, there’s some new side plot that, well, isn’t new I just don’t remember hearing about it earlier.
This is the reason I never got into the Godfather movies and as much as I loved Sopranos always had a hard time following it. Sooo many people, soooo many side plots, then they all intertwine with each other. Just too confusing. I have enough trouble keeping anything more complex then a romantic comedy straight much less something like the Godfather. Too bad, I really do like those types of movies.
Recognizing names, faces. Someone will say, “there’s Mr. Doe sitting next to us, he used to live upstairs from my mother.” “This is Ms. Eliza, our son’s teacher.” I will see Ms. Eliza again at open house and have no idea who she was again. “Look! Look! At the bar is (fill in a name of a middling or even well known celebrity here_____)”. How do they know??? I dread the day my mom dies, partly because all those people at the funeral will be - who are you again, and how did you know my mom?
Social talk in general, children in particular. Large or small - what the heck do you talk to them ABOUT? I try, I really do, I quiz them about their tastes in music but I can just hear them thinking, go away, idiot, while they fiddle with their cell phones. Small ones? “so…how old are you now? So…want a cookie? So…want to go and watch cartoons till mommy comes back?”
Insurance, and anything connected with it - medicaid, medicare, deductibles, premiums. Can’t quite grasp it, even after someone patiently walks me through the process.
(math)
Drawing. My attempts at drawing stick figures have been mistaken for Jackson Pollock originals.
I’m a math major, but I always think it’s funny how many people think that means human calculator.
“Hey Joe, this dress originally $135, it’s 20% off, then another $10 off then $15% off that, how much will it be with tax?”
“Umm, err hold on…”
“You can’t do that in your head?”
“No, why would you assume that?”
“Well you’re a math major”
“Yeah, but it’s not that I spent four years doing arithmetic, you want to know the derivative of the original price, I can give you that though” (it’s zero)
Having said that, I am actually okay at doing this kind of thing in my head.
I cannot start nor finish anything. It’s a mystery exactly what I do all day or how I do it.
Self motivation.
Conversations with the opposite sex.
Sport.
Not uncommon, I imagine, especially amongst the nerdy set; a group I fit within rather comfortably.
I am almost certainly some version of a sociopath just like my father and a few other members of my family are. That is more complicated than it sounds (I am not a criminal in the least and I do have my own set of values) but I don’t experience the same range of emotions that other people seem to especially when it comes to bonding with other people. A lot of the moral dilemmas people throw out sail right over my head. I like everyone until they may make me mad and then I either want them dead or their life destroyed and would I would love to help speed that process along given the chance. Only people biologically related to me get a partial pass on that. I can have a good relationship with someone for years and then turn on them completely and permanently given a minor change in circumstances. The best I can do is be aware of this fact but I don’t think I can change it. I can’t ever get married again for example because there is no way it will work out well for the person in question and I won’t even care.
I can’t draw for shit either.
Seems I’m not very good at holding down a job.
I have no sense of direction. I have tried and tried to develop one, by studying maps of my area and trying to teach myself how to figure out which way is which, but it’s completely hopeless. I’m a little better after having lived in this area for going on five years now, but I still routinely get lost within a mile of my own neighborhood. I just always seem to pick the wrong direction when I’m not 100% sure which way to turn. My mom got me a GPS for my car two years ago, and it has changed my life.
Heh, what I used to get was “oh, I don’t know how you can do it” (“it” being “doing math”). But to be honest, the more I study math the more I don’t know how I do it either. That stuff is hard, and I’m actually good at it! But now I’m really acutely aware of how much I don’t know.
That juxtaposition made me crack up. Arson, murder and jaywalking?
