Problems are not stop signs, they are guidelines.

Without hard work, nothing grows but weeds.

By failing to prepare, you are preparing to fail.

Be gentle to all and stern with yourself.

Always desire to learn something useful.

To be a good loser is to learn how to win.

To know oneself, one should assert oneself.

Things do not happen. Things are made to happen.

If you've got a talent, protect it.
