“There is one purpose to life and one only: to bear witness to and understand as much as possible of the complexity of the world -- its beauty, its mysteries, its riddles. The more you understand, the more you look, the greater is your enjoyment of life and your sense of peace. That's all there is to it. Everything else is fun and games. If an activity is not grounded in "to love" or "to learn" it does not have value.”
