Industry is not only the instrument of improvement, but the foundation of pleasure. He who is a stranger to it may possess, but cannot enjoy, for it is labor only which gives relish to pleasure. It is the indispensable condition of possessing a sound mind in a sound body, and it is the appointed vehicle of every good to man.

Robert BlairThat discipline which corrects the eagerness of worldly passions, which fortifies the heart with virtuous principles, which enlightens the mind with useful knowledge, and furnishes to it matter of enjoyment from within itself, is of more consequence to real felicity than all the provisions which we can make of the goods of fortune.
