I would have told my mom when the babysitter’s boyfriend started touching me ‘bad’ when I was 4.
I would have hit Shamra Burke back w/ a truncheon the first time she punched me for being different instead of being her personal punching bag till 8th grade.
I would have stuck w/ college right out of high school, rather than blowing it off b/c I was so immature and short-sighted; wasted 13 years and now I’m scrambling to get my degree in 4 years.
I would have been kinder to and more tolerant of my friends and listened more than I talked. I should have been right less and happy more.
I would have gotten up a little earlier and walked to work less than a mile for the 6 years I worked next door to my apartment complex. The dryer was not, in fact, shrinking my pants.
And the biggie? I would have waited until I was married to have sex; it has yet to be worth the aggravation premarital sex can bring.
I probably wouldn’t have majored in anthropology. I think I’d have studied political science or something closer to my career goals. However, anthropology was closer to my career goals at the time, so meh. I can’t get too upset.
Recently: I wouldn’t have had my nose surgery last month. It was elective, my doctor did not give me a good idea of how unpleasant the recovery process would be, and so far I do not think it was worth the trouble. (I guess I can breathe a little better, but it’s not like I was gasping for air before, and the two days following the surgery were the worst. days. of. my. life.)
I should have gotten a job straight out of collage rather than starting my own business and loosing almost a million bucks (inheritance) and going another quarter mil in the hole and finally starting my career 10 years late in bankruptcy and debt with two small children.
And I would have gotten divorced many years earlier than I did (16 years of marriage).
I would have lost weight as soon as I started gaining it, instead of having to lose about 100 lbs now because I ignored it for 8 years. Also, I would have broken up with my ex when I realized it wasn’t working out instead of trying to force a relationship that hadn’t worked in a long time.
I would have NOT joined the Navy straight out of HS and, no matter how hard it seemed at the time, gone straight into college. Starting 6 years later with a full time job and family was a lot harder.
There’s also a certain skateboarding incident I would prefer to have skipped, and the surgery that followed it.
I would never have been part of a negotiating team, nor would I have spent so much time and effort on a lot of related work, without compensation.
This is an interesting question.
I mean, there are plenty of things I regret, but I’m not sure I’d change any of them because I learned something from each and every one of those bad experiences–I learned something about myself, others, human nature, trust, whatever. And typically, something positive came out of each negative.
My experiences made me the person I am today, and I kinda like me. 
A girl, who I have known as a friend of a friend in university, had broken up with her boyfriend. I did have a crush on her, however I was too chicken to ask her out. I should have taken the chance.
I wouldn’t have become a drug addict and wasted five years of my life.
…do all those drugs.
Yeah, I was an anthropology major also. I would not do it again. Learned some interesting stuff, but nothing practical. It was essentially a waste.
I would also not spend 20 years believing in the myths of socialism. What a colossal waste.
