Be gentle to all and stern with yourself.

Do not weep do not wax indignant. Understand.

I can, therefore I am.

Know or listen to those who know.

Begin to be now what you will be hereafter.

If you've got a talent, protect it.

By failing to prepare, you are preparing to fail.

Things do not happen. Things are made to happen.

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