If you could go back in time and learn about a certain topic or skill what would it be (assuming you'd be in the same profession you're in now). Please also mention what field you're in.
Wanted to wait on my own response so as not to influence peoples' responses. I'm a software developer and I've recently been thinking that one of the skills that I'd like to improve on is writing. Never late to work on, but it would've been great to put a little more effort into it earlier in life.
I don't think it's ever to late to learn something. I'm kinda on the fence about learning / trying to get into theoretical science and physics. I find a lot of the space science stuff happening lately to be very interesting and I'd love to try to prove (for example) black holes exist (or don't)
I wish I had explored more artsy endeavours in high school and college, instead of being such a nerd focused on only science. Litterature, drama, creative writing, music.
