To know oneself, one should assert oneself.

Know or listen to those who know.

If you think you can do it, you can.

Who seeks shall find.

Go for it now. The future is promised to no one.

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

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

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

You never know what motivates you.
