To me, being successful means...
Feeling inspired and surrounded by love and support. If I can lay down at the end of every day and know that I am following my heart, however hard the journey, then my life is a success.

My definition of success has changed over time. 
Growing up, in Palo Alto, especially, I really thought that the only positive or desired future was one with wealth, and even some amount of fame. I didn't see another option for happiness.
