Alan Lightman said this quote

The tragedy of this world is that no one is happy, whether stuck in a time of pain or joy.

~ Alan Lightman

Two men who had never seen each other before and would not likely see each other again. But their sincerity and sweetness, their sharing an instant in a fleeting life. It was almost as if a secret had passed between them. Was this some kind of love? I wanted to follow them, to touch them, to tell them of my happiness. I wanted to whisper to them: 'This is it. This is it'.

~ Alan Lightman

If a person holds no ambitions in this world, he suffers unknowingly. If a person holds ambitions, he suffers knowingly, but very slowly.

~ Alan Lightman

Each person who gets stuck in time gets stuck alone.

~ Alan Lightman
