(Motivation comes from the brain,
Inspiration comes from the heart.)
First off, you have to define success. Success is related to you and how you see yourself within society. For one person success is merely living each day in health and fulfulment, while for another it is earning more than $100,000 a year. If you feel like you have succeeded, you have; however, that might not be "societies" opinion. But does that even matter?
I think this homework requires you to take a look at your own concept of success which will in turn reflect your position within your culture (mainstream or not).
For me, I'm not really motivated to succeed...but I am inspired to better myself each and every day.
