Yes, I am self-confident.
I’m not sure what it looks like, it doesn’t exactly display explicitly. One example is that I’m always willing to try new things and just do stuff; I don’t hold back like some people I know. I have a friend who often doesn’t want to do things (like games, sports, or other things that require some kind of ability) because he thinks he’ll bad at everything. I think I’m intelligent and I don’t let people tell me otherwise. I’m confident in social settings; I’m not a leader type person by nature so I don’t tell people what to do or anything, but I’m not afraid to voice my opinion whenever I feel it necessary.
Sometimes I just plain think I’m awesome. I don’t impose it on anyone else, but I don’t let things get me down. I don’t let people take me down, it’s harder than it looks to do that to me. :)
And I like I always always stress: I’m not arrogant. I don’t think I’m better than other people. I just think I’m really great. :P
