Be gentle to all and stern with yourself.

Do not weep do not wax indignant. Understand.

Without hard work, nothing grows but weeds.

If you think you can do it, you can.

To know oneself, one should assert oneself.

Well done is better than well said.

Leap, and the net will appear.

It's always too early to quit.

By failing to prepare, you are preparing to fail.
