Today, I went to the dentist. Not being a fan of people picking up teeth, cramming stuff in my mouth and being all up in my personal space (granted they were just doing there jobs)... I remembered this wisdom from two sagely Klingons.
I'm just saying.
And if you want to find a more "spiritual" application, here's one by a fellow pastor. Although comparing going to church to going to the dentist doesn't send thrills of excitement up my spine... more like chills. But he does have a point about independence and self-sufficiency.
