Artists, Photographers and Winemakers Face Fear

At one time I lived in the drawing and painting art world. (I even ended up with a Master's Degree in Fine Art.) During that Painting Period of my life and now with photography, I noticed that after a very successful painting or gallery show, some artists (myself included) would fear to continue. A chilly inner voice whispered: "How can I do anything that good again?" So it was safer to continue using the same "successful" technique. For me that meant death to strong new work.

I wonder if winemakers experience the same "fear" after a successful wine? And worse yet, winemakers only get one chance a year. At least for me, when I do a bad photo, the next exposure is a new opportunity.

And how can an artist, photographer or winemaker get past this fear?
