Know or listen to those who know.

Be thine own palace, or the world's thy jail.

Things do not happen. Things are made to happen.

It's always too early to quit.

Problems are not stop signs, they are guidelines.

If you think you can do it, you can.

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

Leap, and the net will appear.

By failing to prepare, you are preparing to fail.
