Too many what ifs

To be honest I have way more advice than I receive mainly because I am stubborn and don't listen to other people or don't ask for help. When I do ask for advice it is either from my close friends, or my mom. I stress out about pretty much everything, but that is the perfectionist in me. The best piece of advice I have ever gotten was, If it's not okay, it's not the end. I've been told this quite a few times and it always seems to clam me back down, take a step back, and think to myself its going to be okay. I get caught up in the moment and often forget that time can change a situation drastically. Any one really close to me knows I stress a lot. I do the whole what if thing and forget to breathe and relax. My best friend found that somewhere, I think, and she tells me that a lot and it calms me down. Another piece of advice that has stuck with me, well I don't know if it is as much advice as much as it is a form of good luck. Before I go on stage, Diana always tells us to give them hell. We haven't really been able to figure out why but it works.
