To know oneself, one should assert oneself.

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

What you do today can improve all your tomorrows.

Always desire to learn something useful.

Begin to be now what you will be hereafter.

Well done is better than well said.

I can, therefore I am.

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

By failing to prepare, you are preparing to fail.
