My persistence. If I really want something pretty much nothing can stop me from going after it but myself. Sometimes I don't know when to quit though. If I find something I really like and isn't just another distraction to me I'll pour everything I have into it but again sometimes it's too much and I get burnt out.
I could really work on finding balance in the things I choose to do.
I've been told by several therapists over the years that I'm insightful
And even though I've gone to the last shred of hope at times I never give up
I'm gonna change my answer to everything and nothing. I think true confidence comes from a place of acceptance rather than thinking of things you feel confident about. When you are confident in doing something you are not thinking about what you're doing, you just do it. It's almost as if it's not you who is doing, you lose the overwhelming sense of self-consciousness, you lose "yourself" in what you are doing.
Edit: For instance, if when walking you're thinking about how you're walking, you are self-conscious about how you're walking. When you allow your natural confidence to surface you are just walking.
So true confidence in oneself would be self-aware but not self-conscious. You wouldn't need to think about yourself, you would do. You would just do you.
