Never complain and never explain.
The dog that trots about finds a bone.
What you do today can improve all your tomorrows.
Be thine own palace, or the world's thy jail.
The secret of getting ahead is getting started.
Expect problems and eat them for breakfast.
If you think you can do it, you can.
Things do not happen. Things are made to happen.
Begin to be now what you will be hereafter.
By failing to prepare, you are preparing to fail.
Composers shouldn't think too much - it interferes with their plagiarism.
