Never complain and never explain.

Things do not happen. Things are made to happen.

Begin to be now what you will be hereafter.

Leap, and the net will appear.

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

If you're going through hell, keep going.

If you think you can do it, you can.

If you can dream it, you can do it.

Know or listen to those who know.
