That's kind of how I feel about it. However, if you aren't doing custom pieces, I don't think you will see as much of it.
My idea (and keep in mind I am not trying to live off this) is to build a little inventory and just sell what I have already made. I don't wish to be a business man again.
When people ask if I'll make a certain item, and I want to make it, then I tell them if I make one of those I'll let you know. They can buy it or not.
And be firm on your price, my boss has finally taught me that. Not everyone does "blank", and those that do don't do it for free.
