What isn't worth it?

There was a question posed on a television show I was watching lat night. The question was referring to having kids, "What makes it worth it?" That got me thinking about what was worth it:

Waking up in the morning with his face right in front of mine,"Daddy, don't you want to play with me?", the big hugs and kisses. "Daddy, I love you sooo much." The dance he does while watching almost any show with music, and now learning the words to those songs. The infatuation with the Police, Fire, and all emergency departments. The list goes on and on, I could sit here and write everything he does.

What my question now is "What isn't worth it?"

I love you buddy, thank you.
