stop looking outside

If you could instantly master any skill, what would it be and why?

I am not sure this is a skill but I would like to take my own advice. I would love to actually live my life according to my own standards. And the most important one is that I should stop looking outside of me for value. No community, no institution, and no person will ever give me value when I do not value myself. The impossible dream!

Or maybe play a musical instrument or be able to draw? Or maybe swimming?
