Okay this may sound abstract.....when you buy an object which has been crafted to perfection by another artist....you dont just buy the object ....it feels like you almost bought some of that perfection...it feels like maybe it can breathe some perfection into your work!
On a cynical note maybe it makes it easier for you to justify the amount of hard work that you put in perfecting every infinitely minute detail in your work.
It is also comforting to know that there are people out there who value perfection and attention to detail like you.....and when you show them your work they'll see all the hard work you have put into it.
