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

By failing to prepare, you are preparing to fail.

Well done is better than well said.

Problems are not stop signs, they are guidelines.

If you think you can do it, you can.

To know oneself, one should assert oneself.

If you can dream it, you can do it.

Be gentle to all and stern with yourself.

It's always too early to quit.
