I can, therefore I am.

Do not weep do not wax indignant. Understand.

Begin to be now what you will be hereafter.

Well done is better than well said.

Know or listen to those who know.

By failing to prepare, you are preparing to fail.

What you do today can improve all your tomorrows.

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

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