Find and follow your bliss. It's okay if your bliss changes.
/To me, being successful means...
finding something that you're passionate about and following that passion. realizing and living your dream(s).
My definition of success has changed over time.
The older you become, the more perspective you have about things. You have experiences to think about. You see how others have dealt with having success or you meet others who feel like they haven't been successful yet.
