Ah confidence. That elusive *****.
I have very little confidence in most things I do (acting/singing aside; I'm hella good at that, lemme tell ya), and sometimes it's noticeable. I've been working on trying to improve it by willing myself into making more friends and not being as intimidated by people. I started this process with eye contact; I usually don't look at people's faces when I talk to them/they talk to me, so I've been trying to look them in the eye when they do. It's helped a lot, honestly. It's not really as bad as people make it out to be, and it's really comfortable since you don't have to feel awkward about looking somewhere else on them. I wanna go to the next step of "talk to people you want to be friends with" and "add them on Facebook if you wanna be friends", but that'll take time.
Normally, I adorn two personalities when in social situations: very open and carefree around friends, very closed and quiet when around new people/people I don't like. It's really hard to maintain them all the time, especially when they get mixed up in a group of people. I'm really trying to be open to everyone but it's really difficult because I really don't like people at all.
