God does not want us to be living in the past, in shame, in fear, or in the future, in worry. He wants us to be living in the present, in now, with Him.
Just let the artist sign an empty canvas or a frame, with the inscription, 'I had such and such a concept in mind' for this work. The artist then need not bother with producing the work, and therefore need not be worried about being dis-satisfied. All he or she needs to do is to sell it to a collector. The collector will have the guarantee that the artist thought about the work, even if momentarily, and therefore be satisfied.
