Well done is better than well said.

Always desire to learn something useful.

By failing to prepare, you are preparing to fail.

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

The dog that trots about finds a bone.

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

To know oneself, one should assert oneself.

If you can dream it, you can do it.
