Be thine own palace, or the world's thy jail.
If you've got a talent, protect it.
Go for it now. The future is promised to no one.
Begin to be now what you will be hereafter.
Without hard work, nothing grows but weeds.
What you do today can improve all your tomorrows.
The dog that trots about finds a bone.
Be gentle to all and stern with yourself.
The secret of getting ahead is getting started.
The wise does at once what the fool does at last.
The object of pure physics is the unfolding of the laws of the intelligible world the object of pure mathematics that of unfolding the laws of human intelligence.
