Why is creating a painting like going to the grocery store?

There are options on how to shop for food, just as there are on how to create a painting. When shopping   A) One can just go grocery shopping and buy what strikes one’s interest once there. B) One can write a shopping list before going shopping, and then zoom all over the store looking for those items. C) One can write the list according to the layout of the store and pick up the listed items in an orderly fashion. D) One can make the list knowing the store layout, and still deviate from the list as inspiration strikes.

In painting, as in grocery shopping, planning and inspiration combined can produce the most interesting results.
