'Tis a maxim with me to be young as long as one can: there is nothing can pay one for that invaluable ignorance which is the companion of youth; those sanguine groundless hopes, and that lively vanity, which make all the happiness of life. To my extreme mortification I grow wiser every day.
Lady Mary Wortley Montagu (1690 - 1762)

Whoever will cultivate their own mind will find full employment. Every virtue does not only require great care in the planting, but as much daily solicitude in cherishing as exotic fruits and flowers; the vices and passions (which I am afraid are the natural product of the soil) demand perpetual weeding. Add to this the search after knowledge. . . and the longest life is too short.
