Do you undervalue yourself as an artist?

I think most of us do.  I recently ran across this saying:

I would like to think that's true, but I'm not so sure.  People seem to always be looking for a bargain or wanting something at a discount.  When it comes to hand crafted items or original art, that saddens me.  

I you are looking for someone to quilt something for you cheap and fast, don't come to me.  My time is valuable and my creative skills are worth more than that.  If you are looking for a portrait done while you wait, that's just not going to happen.  Creativity isn't measure in dollars or hours, but in inspiration.

How do you price your services or creations?
