This might sound kind of inspirational but as someone who feels similarly to OP, that's a long list of things that I would never want to do. I don't want to do anything - that includes the random list that you're throwing at the wall. It's not like I've always wanted to have a different job, travel or learn more languages and I'm too timid to try these things - I don't want to do anything including all of the things you mentioned.

Change is a good thing but removing all of the stability from your life and spending all of your time doing things that you don't want to do seems like a really bad idea.
