I'm confident in the sense that I have accepted myself. I don't hesitate to say what's running through my mind. I consider myself to be a nice person, but definitely a more aggressive/reactive one as well.
More than anything, I try to enjoy myself and what I'm doing. Whether that's studying, working, or doing something more in-line with enjoyment, I think it's important to always be having fun and trying to stay positive.
I'm still young, trying to enjoy it, and just attempting to make it by with what I have.
