If you think you can do it, you can.

Things do not happen. Things are made to happen.

The most effective way to do it, is to do it.

To know oneself, one should assert oneself.

If you can dream it, you can do it.

What you do today can improve all your tomorrows.

I can, therefore I am.

Leap, and the net will appear.

Well done is better than well said.
