Leap, and the net will appear.

I can, therefore I am.

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

It's always too early to quit.

Know or listen to those who know.

Things do not happen. Things are made to happen.

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

Begin to be now what you will be hereafter.

By failing to prepare, you are preparing to fail.
