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

Either you run the day or the day runs you.

To know oneself, one should assert oneself.

Be gentle to all and stern with yourself.

Know or listen to those who know.

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

Well done is better than well said.

After a storm comes a calm.

By failing to prepare, you are preparing to fail.
