Comfort Zone

Do you watch The Big Bang Theory?  The nerd humor cracks me upon a regular basis!

In any case, in a recent episode, this exchange appeared:

Penny: "Okay, but let's try to get you out of your comfort zone."

Sheldon:  "Why would we want to do that?  It's called a comfort zone for a reason!"

I laughed pretty hard.  These are my feelings on a comfort zone.  Why leave it?  It's called a comfort zone for a reason.

That said, I've spent a lot of time outside of mine lately, and I will concede that there is much to be learned outside of it as well.
