Do everything you do for its own sake.
  • Yesterday is a bucket of ashes that won’t burn again
  • Tomorrow is a dream you may never see.
  • Life isn’t a destination, It’s a journey…
  • And every day -- as good or as bad as it might seem --
  • is the best of all possible days.
  • Where does new knowledge come from? ...
people create new knowledge
People create new knowledge:
  • Analysis AND synthesis
  • Discovery...
  • “Seeing what others have seen and thinking what no one has thought.”
  • Seeing the world from new directions and understanding a new dimension...
slide18
“There is a time in every man\'s education when he arrives at the conviction that envy is ignorance; that imitation is suicide; that he must take himself for better, for worse, as his portion; that though the wide universe is full of good, no kernel of nourishing corn can come to him but through his toil bestowed on that plot of ground which is given to him to till.

“The power which resides in him is new in nature, and none but he knows what that is which he can do, nor does he know until he has tried.”

Ralph Waldo Emerson in Self Reliance

  • Drive out fear to avoid minimax regret
  • Reward Process rather than short-term results
  • Rational Laziness is a virtue
  • Unemployment is the goal
