I've concluded that my purpose is to provide support
I can definitely identify with this. I don't think I'll ever be anything that great myself, but I like supporting other people in reaching their goals. It doesn't even have to be anything incredible; I simply like supporting people in their lives. I dedicated a lot of myself to my husband so that part is getting reshuffled but I don't think I'd ever call that my purpose anyway. The purpose I've given myself is simply to help people, and better myself along the way.
Also the world is far too curious a place for me to ever get bored.
