How people treat you is their karma; how you react is yours.
Wayne W. Dyer
Science is organized knowledge. Wisdom is organized life.
Even if you are on the right track, you’ll get run over if you just sit there.
Do the best you can, and don't take life too serious.
You cannot swim for new horizons until you have courage to lose sight of the shore.
Time moves in one direction, memory another. We are that strange species that constructs artifacts intended to counter the natural flow of forgetting.
