As an ardent practitioner of 'lazy' and an expert on the subject, I can speak with authority that Buddhists are not lazy. Lazy is going to the church you grew up in so you don't have to think. You know with absolute certainty that God is a Republican and all is well.

Someone not born into buddhism but chooses to practice it, has made a strong and arduous commitment. He/she has chosen to exercise the muscle between his ears and follow a philosophy in accord with his own conscience.
