I can, therefore I am.

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

Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.

Without hard work, nothing grows but weeds.

Expect problems and eat them for breakfast.

The secret of getting ahead is getting started.

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

By failing to prepare, you are preparing to fail.
