Chants: Shave it! Shave it! Shave it!
Suppose I put something on my schedule that I may or may not succeed in doing - e.g. rob the bank. Am I disqualified the first time I try but fail to break into the bank vault in my frozen hour?
ETA: Or something that’s not happening every week, like go to a Nats home game.
Funny to see the OP’s list. Since I’m retired, I can read, listen to music, or nap anytime I want to. Or teach myself to play the piano, since I’ve never played.
Nah, it’s the effort that counts. I’m sure you’ll do better next week.
That would be a pretty dumb thing to pick knowing that you won’t be able to complete it every week. Not to mention, it won’t be much of a game. 
I am also retired, and I can do those whenever I want, too. But having a bonus hour every day would be quite enjoyable and would allow me to get better at piano faster, get more stuff read, or get more nappage in.
mmm
That, I am afraid, is not how it works. That’s why I have opted for mischief I would never get away with otherwise. Such a magic power must not be used for fighting procrastination, as it will only lead to more procrastination. My problem is not lack of time. It is lack of opportunity (for mischief) or lack of motivation (for sensible things). So, as I don’t have to do it, as you generously grant us the opportunity to sit it out every time, I choose to be able to do things I otherwise could not. Having more time to do the things I am not doing anyway is no good.
Your logic is unassailable.
Agreed. @Pardel-Lux wins the thread.
To each their own, I guess.
I envision stopping the world at 2:00 and settling down with a good book for a (very) quiet hour of reading.
And, when I’m done, it’s still 2:00.
mmm
How did you get a copy of my Resume?
To each their own indeed. With no disrespect intended, your plan seems an utter waste of a unique opportunity. The world effectively stops for me whenever I sit down to read.
As someone said upthread, it depends a bit on how busy you are. What 30-something working parent hasn’t wished for an extra hour (or 6) in the day just for themselves? I’m a single retired guy with zero obligations to anyone or anything. All 24 are all for me every day.
Uh oh. @Elmer_J.Fudd mentioned surfing upthread.
So how would the oceans work? If the waves are frozen in time and space, can our hypothetical person walk around on them?
Banks, relatively, don’t have much cash. Go for an armored car!
That’s too much shoplifting & stealing; I’m thinking of a certain scene from Porky’s for at least one day. 
That’s when I stopped reading the thread until I got a mention notification. I have enough spare time to screw around on the Dope everyday; so supernatural spare time isn’t much of a fantasy for me unless it frees up resources that would otherwise be limited like unriden waves. I could see the appeal if I was currently a full time caregiver of some kind, though.
I think I would just opt out. Even shoplifting, robbing armored cars, and pranking the Former Guy would get old if I was on a schedule to do them. The blissful part of retirement is having no schedule.
ETA: I read The Girl, the Gold Watch, and Everything when I was maybe 14 years old. Read it a few times, actually - it was a fun book. The thing about Kirby and Bonnie in the story is that they can use the gold watch to stop time for one of them whenever they want (for up to an hour at a time), and if they don’t have a reason to, they don’t. Having that gold watch would be a blast.
Having time automatically stopped every day where you had to use (or try to use) the time for some fixed purpose every time…fuhgeddaboudit. That would be kinda like work, and I’m blissfully done with work.
Yeah, I look forward to retirement for that reason.
I’d probably use 1:00 am and choose sleep as my extra activity. I don’t live alone and other people frozen around me would just be uncomfortable. This way I get an extra hour of awake time (can stay up later) without the weirdness being so overt.
No matter how nice the activity I choose, I certainly wouldn’t choose any time frame that would keep me at my place of work longer.
I think you’re onto something for the most fun version of this hypothetical.
Plus of course @Elmer_J.Fudd’s implicit comment that many fun activities depend on motion in the world, or my explicit comment waaay upthread about motion with other people. So the user’s ability to punch a few controlled holes in the total freeze for entertainment’s sake would be ideal.
I suspect the OP’s intent was probably closer to “What utterly solitary activities would you enjoy doing so much that you could commit to them for an hour a week for a year with zero exceptions and zero interruptions?” And then he came up with “freezing the rest of the world” as a MacGuffin to cause the enforced solo participation in your activity with total uninterruptibility.
And then of course we seized on the MacGuffin as the whole point. We’re Dopers; that’s what we do!
Not exactly. My thought was more like, “if I had one extra hour per day, and nobody else did, how would I use it?”
My first inclinations were: more reading time, more piano time, and more nappage.
But I really like the rob-a-drug-dealer suggestion, too.
mmm
