I bet you could sometimes find all the mysteries of the universe in someone's hand.

I cannot teach anybody anything. I can only make them think

When you kill time, remember that it has no resurrection.

I have realized that the past and future are real illusions, that they exist in the present, which is what there is and all there is.

Time is a slippery thing: lose hold of it once, and its string might sail out of your hands forever.

The main problem with this great obsession for saving time is very simple: you can't save time. You can only spend it. But you can spend it wisely or foolishly.

Time is the coin of your life. It is the only coin you have, and only you can determine how it will be spent. Be careful lest you let other people spend it for you.
