To know oneself, one should assert oneself.

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

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

Know or listen to those who know.

If you can dream it, you can do it.

I can, therefore I am.

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

Never complain and never explain.

If you're going through hell, keep going.
