I Am Lost In Life

My outlook on life changes every single day, and that might not seem like a big deal but it's borderline life crippling. I'm 30 years old with no college degree and make more money bartending in Vail Colorado working 30 hours a week than the majority of my college graduate friends in professional fields. But I am increasingly more and more unhappy with it. I have absolutely no pride in it or my life in general. Which is odd because I live comfortably in a place some people are only able to dream of going to. All my life i planned on going to college, I still do, I never expected to be so late with it but for the life of me I have no idea what to go for. One day I know exactly what I want to get into, I'll obsessively research the field and decide that that's what I'm going to do. But then I wake up the next day thinking it's all foolish and fall back into a state of contentment in the fact I have never really tried that hard in life. I can't find motivation, I can't commit, I can't decide on anything. I'm just stuck in life and have been for a very long time.
