Think about it. To me, and I see WK agreed, to be a painter means that you are an explorer. Never satisfied with what you can do, you are forever searching. That said, you if you are genuinely searching you can't have a technique you rely on to create a certain effect. Even if you paint the same thing every day, the concept is different.
I learned this long ago. When I was studying for my MFA I spent two full years painting a pot of yellow mums. Yes, I did have to keep buying new yellow mums when the fresh pot withered away completely, but it was always the same size yellow mums. I can tell you I learned more in those two years painting those mums. I learned about painting and endless possibilities. I continue that work now as I paint the same block of trees, or the same soccer field near my house. Sometimes I feel like Magellan as he rounded Cape Horn and discovered the other side.
What happens if I do this?
