Starting Over

Okay, so college! Yes I know I will get a ton of flack for going to an Online college but it fits my needs, currently car-less and job hunting I need the freedom to set my own hours. University of Phoenix seems like a good fit, plus it fits one of my requirements, no entrance exams. I doubt I could pass. its been a long time since High School, and while I was never very good at it in the first, the school i went to didn't require me to take several of the classes a a regular high school would have. Ahh, did I forget to mention I went to an Alternative High School? For me the alternative was no school. I went through a difficult time in my life and very easily could have been a dropout, I did in fact dropout 2x. Anyway it all adds up to having a lack of confidence in my own abilities, and I am the type of person if i examine things too closely, I don't follow through. Hence no entrance exam. If I failed or barely passed, I would have more insecurities than just jumping in or at least that's the theory. So once again I am jumping in with my eyes half closed, wishing for the best, and I wonder why my life doesn't work out? lol. I feel like I am starting from scratch, that I have to learn everything all over again, and I wonder, does everyone feel some version of this? or is it just me?
