Personally I would say to my 20 year old self, (I'm about to turn 30): Write more code, lean into it, don't avoid it. (I have a masters in mechanical engineering, but I ended up writing code anyway in a tech company.) Do more public speaking. (I still get unreasonably anxious about this and I feel like I suck at it) Stick to hobbies and exercise (I'm a perpetual beginner in several things, I am not consistent at practicing guitar, or at rock climbing, two things I love and would like to be better at. It's generally more enjoyable to be somewhat decent at things.) Read more books (and make 1 in 10 of those a fiction book, I read too much non-fiction business/technical/startup books) Do more online courses (It took me ages to finally get around to doing things, I completed CS50x and some FreeCodeCamp stuff and I enjoyed it a learned a lot.)
