My point is that when I was eager for it, dollars were a great metric for my hourly value. Now, personal enjoyment, or feeling like I'm doing something valuable with that time has a much greater importance.
I feel the same way now that I have a daughter (10 months old). I work full-time, but I have always done the odd freelance or consulting job on the side...a few hours in exchange for a few extra bucks used to be worth it. Now, I'd rather spend that time reading to my daughter, or watching her figure out how a toy works.
