Man is the only creature that refuses to be what he is.

Your mind is a powerful thing. When you filter it with positive thoughts, your life will start to change.

How wonderful it is that nobody need wait a single moment before starting to improve the world.

You see things; and you say, ‘Why?’ But I dream things that never were; and I say, ‘Why not?’

If you think you are too small to make a difference, try sleeping with a mosquito.

If you feel safe in the area you’re working in, you’re not working in the right area. Always go a little further into the water than you feel you’re capable of being in. Go a little bit out of your depth. And when you don’t feel that your feet are quite touching the bottom, you’re just about in the right place to do something exciting.
