For me it is not so very important at all how super smart or brilliant someone might be or whatever kind of fantastic education one has had.
The most important thing is how well one uses this knowledge in selecting creative and original tid-bits in order to accomplish the most with the least.
Choosing the middle-path when appropriate, forsaking perfection for a better reality.
Common-sense, down-to-earth, to the point, faith in oneself, perseverance, and the courage to give up in time and be honest even if it means failure.
When in fact it means success of the highest kind.
