"Ambition is never content, even at the summit of greatness." ~ Napoleon Bonaparte
Keep away from people who try to belittle your ambitions. Small people always do that. But the really great, make you feel that you, too, can become great.
All professionals have "drive. Ambition. And the cold, rational ability to compartmentalize tragedies...and carry on." ~ Dario Arapovic (Brother Ameen)
