If you think you can do it, you can.

Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.

Know or listen to those who know.

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

If you're going through hell, keep going.

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

Who seeks shall find.

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