It's always too early to quit.

Be gentle to all and stern with yourself.

If you think you can do it, you can.

Things do not happen. Things are made to happen.

The wise does at once what the fool does at last.

Leap, and the net will appear.

If you can dream it, you can do it.

If you've got a talent, protect it.

To know oneself, one should assert oneself.
