If you can dream it, you can do it.

It's always too early to quit.

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

To know oneself, one should assert oneself.

Be gentle to all and stern with yourself.

Do not weep do not wax indignant. Understand.

Well done is better than well said.

If you think you can do it, you can.

I can, therefore I am.
