Defining success is almost like talking politics or religion. Everyone has their own view.
I gave it some thought last night, and here is what success means for me:
You know what you are made of, you like what you see in the mirror, and you like what you do every day.
Simple. Self knowledge, self esteem, and enjoying your endeavors. You don't need a mansion, you don't need an ambassadorship, and you aren't trading drudgery for material gain. It is a fairly simplistic definition, but I think it is profound. Given how people in this industry strive, work and deal with adversity as part of our daily routine, I think it puts things into perspective.
