it is like being an artist (let's say a painter). You spend 9 months day in and day out painting a "Mona Lisa". You better make sure all the notables like your work. If not you may as well have been working for the love of it because the guys who walk in the gallery will only eat your cheese, drink your wine, have a quick look at your painting and at best comment about it. But no money will be spent. Well unless you manage to sell them premium wine and cheese.

EDIT: @Diego. Had I read you comment, I would probably write mine differently. Apologies.
