Without hard work, nothing grows but weeds.

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

What you do today can improve all your tomorrows.

Well done is better than well said.

The wise does at once what the fool does at last.

Always desire to learn something useful.

Leap, and the net will appear.

Problems are not stop signs, they are guidelines.

To know oneself, one should assert oneself.
