Hi duus, I've been thinking about this a bit lately too. I think it would help to take a step back from your own life and see yourself as a character with endless possibilities for skill improvement and acquisition. You get to write this character's story and decide which skillsets are important to gain experience in.
Have you made any progress in developing a "character sheet"? I'd like to hear about it if you have, and to help in some way if possible. Thanks!
