Well done is better than well said.

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

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

If you think you can do it, you can.

If you're going through hell, keep going.

If you can dream it, you can do it.

By failing to prepare, you are preparing to fail.

To know oneself, one should assert oneself.

I can, therefore I am.
