I can, therefore I am.

What you do today can improve all your tomorrows.

By failing to prepare, you are preparing to fail.

Be gentle to all and stern with yourself.

Things do not happen. Things are made to happen.

Begin to be now what you will be hereafter.

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

Problems are not stop signs, they are guidelines.

If you've got a talent, protect it.
