Here is the quote that I slaughtered the other night when trying to give an example of C.S. Lewis' uncanny ability is to concisely convey a profound thought.

Here was my version:

"The ability to do and feel decreases when we fail to do. And then, in the long run, we begin to not feel."

Here is the actual C.S. Lewis quote:

"The more often [one] feels without acting, the less he will be able ever to act, and, in the long run, the less he will be able to feel."

Which one do you like better?
