To me, being successful means...
I believe that success is defined as being happy with all aspects of your life. In order to do that, one must work hard to achieve that success. For me to be happy, I want to work at a job that I look forward to going to everyday and that pays well. That means I will need to get a college degree and make myself marketable. Success and happiness are intrinsically linked. I do not believe that you can be truly successful without being happy.

My definition of success has changed over time. 
I always thought growing up that success was all about having a lot of money and living in a big house but that perception changed once I moved out of Palo Alto and went off to college. I also was grown up thinking in high school that if you don't go to an Ivy League school, you will be a failure in life. That perception really changed when I graduated from [high school name omitted].
