How did you figure out what you wanted to do with your life?

I'm turning my life around for the better. I've been educating myself, asking the big questions and trying to find answers. Teaching myself to cope with reality and my own insecurities and limitations. I've only just begun but already I'm feeling a bit better about my circumstances. So it got me thinking. What is it I want to accomplish? Do I want to go back to college? What career path do I want to follow? etcetera etcetera
