Get wealth if you can by honorable means, and if it do not cost too much. A true cultivation of the mind is fitted to forward you in your worldly concerns, and you ought to use it for this end. Only, beware lest this end master you; lest your motives sink as your condition improves; lest you fall victims to the miserable passion of vying with those around you in show, luxury, and expense. Cherish a true respect for yourselves. Feel that your nature is worth more than every thing which is foreign to you.

Self-Culture (1838)
