Success is whatever we want it to be and it seems like defining what that is for us as individuals is the key. I think we are overly influenced by the materialistic culture that we're part of. We are somewhat brainwashed by media. I think our views on what success is are often skewed, off-kilter, and frequently unhealthy. That has been my personal experience anyway. What really matters and why does it really matter? Tuesdays With Morrie was a good book that may give some ideas.
