Sinclair Lewis

He who has seen one cathedral ten times has seen something; he who has seen ten cathedrals once has seen but little; and he who has spent half an hour in each of a hundred cathedrals has seen nothing at all.

Sometimes it's even hard to tell the difference between a tic and a compulsion. But while tics stem from an urge in a specific part of the body - either completely unconsciously or through a premonitory sensation that's satisfied only by the tic - OCD bubbles up as conscious thoughts in the mind.

One misconception is that if we follow God in the life of faith, and that means obedience - that we read His Word, we're obedient, we pray, we go to church, we do the right things - that somehow His blessing means we're going to be okay.
