The secret of joy in work is contained in one word - excellence. To know how to do something well is to enjoy it.
Excellence is not an act but a habit. The things you do the most are the things you will do best.
No one has a greater asset for his business than a man's pride in his work.
One can never consent to creep when one feels the impulse to soar.
If you don't do it excellently, don't do it at all. Because if it's not excellent, it won't be profitable or fun, and if you're not in business for fun or profit, what the hell are you doing there?
