I can, therefore I am.

Begin to be now what you will be hereafter.

Do not weep do not wax indignant. Understand.

If you've got a talent, protect it.

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

Well done is better than well said.

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

It's always too early to quit.

Always desire to learn something useful.
