This. In my little theory, that's exactly the watershed: will one be able to find something exciting to do. If succeeded, learning abilities and creativity follow the energy. It's akin to falling in love, really. But yeah, when you get older, you my need to try harder finding those things.

I couldn't find any tricks as to how to identify such areas of interest, but I "discovered" an indirect factor that raises the chances for that: regular physical exercise, ice baths, proper nutrition, and staying calm. When I feel great, the world suddenly becomes a fun place to live.
