You'll never find rainbows, If you're looking down.

Optimism is important. You have to be a little silly about the goals you are going to set. There is a phrase I learned in college called, 'having a healthy disregard for the impossible.' That is a really good phrase. You should try to do things that most people would not do.

The extraordinary courage and wisdom of Kant and Schopenhauer have succeeded in gaining the most difficult victory, the victory over the optimism concealed in the essence of logic-an optimism that is the basis of our culture.

My view is that at a younger age your optimism is more and you have more imagination etc. You have less bias.

If calamities had the weight of physical objects we should long have been crushed down, or else, we should by now have been hunchbacked, unsteady on our feet, and with faces full of gloom and utter despair. Yet my entire body throbs with life and is full of expectations. Each day brings a fresh stock of experiences and new dreams.

Don't worry about a thing, 'Cos every little thing is gonna be alright.
