Never complain and never explain.
What you do today can improve all your tomorrows.
It's always too early to quit.
I can, therefore I am.
Quality is not an act, it is a habit.
The dog that trots about finds a bone.
Be thine own palace, or the world's thy jail.
Leap, and the net will appear.
By failing to prepare, you are preparing to fail.
Begin to be now what you will be hereafter.
To become properly acquainted with a truth, we must first have disbelieved it, and disputed against it.
The artist belongs to his work, not the work to the artist.
