To me, being successful means...
Acting in a way that was true to my values. That meant for me, dropping out of UC Berkeley half way through my first quarter of my senior year, and travelling....For me, being successful means following my heart...

My definition of success has not changed over time. 
Sometimes I do think I could have been more financially successful if I had been more traditional in my career choices, but I know I would not have been as satisfied with my life.
