Answering the question in the title is hard for me, but I can give you a side tip on this: > I feel immense regret for a lot of things that I didn't do in my 20s. First, it is natural to feel this way. It means you appreciate yourself and your time. Now, the past is past. No matter how much you think about what you did or didn't do, nothing will change your "lost time". The only thing you can change is your future, try to make better decissions using the wisdom you have gained. Finally, if you fail to make the most out of your years to come, don't beat yourself. Failure is the basis for success. We all fail and we use the failures to succeed further down the road. Also, keep a few close friends near you and love them :)
