Uncertainty and Inhibition

Lately, I've been hearing a lot of "You need to work on your college applications!" from my mother, and I'm sure I'm not the only one.  I've put off the applications not because I'm lazy, but because I'm uncertain.  There are a few major turning points in life that can only be experienced once, and graduating from high school is one of these turning points.  Uncertainty leads to worry which leads to fear, and fear inhibits accomplishment.  I think that instead of worrying about the possible failures I could experience, I'm just going to try my best by making my personal statements reflect myself as best as possible.  One of the most worrying parts of applying, though, is choosing a major.  For one of the schools I plan on applying to, Cal Poly San Luis Obispo, a major must be declared immediately.  I'm nowhere near ready to decide what I want to do for the rest of my life.  I know that most people change their minds during college, but I also don't want to waste my time on subjects that I'm not going to pursue, making the already elongated college experience longer.  Of course, the money that it would cost to change majors and start again is a huge deterrent on top of the time spent.  However, all I can do is choose the major that I am most interested in now, ecology, and if it doesn't work out - oh well, then i will have to change majors.  I've spent to long worrying about "what-ifs," and now it is time to go for it.
