I can, therefore I am.

By failing to prepare, you are preparing to fail.

Begin to be now what you will be hereafter.

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

What you do today can improve all your tomorrows.

It's always too early to quit.

Either you run the day or the day runs you.

Wherever you are - be all there.

The dog that trots about finds a bone.
