I'm always thinking I'm messing up. I did a lot of classes. I can't stand being on stage or the only one talking in a room, so class really helped me deal with that. It doesn't really get any easier, but it helps you focus on the acting.
I'm comfortable in any situation. I don't have fears about a lot of things. It's not a survival thing, but on a farm, you always look after yourself. You're very independent, but you're still very family-oriented.
People take years learning how to act; it's a skill, not just a job. If I tried it out and thought I'd be OK, then perhaps I'd go for it, but it's not the kind of thing you can get into just because of your looks.
