When you are producing ideas, you are replenishing neurotransmitters linked to genes that are being turned on and off in response to what your brain is doing, which in turn is responding to challenges. When you go through the motions of trying to come up with new ideas, you are energizing your brain by increasing the number of contacts between neurons. The more times you try to get ideas, the more active your brain becomes and the more creative you become. If you want to become an artist and all you did was paint a picture every day, you will become an artist. You may not become another Vincent Van Gogh, but you will become more of an artist than someone who has never tried.
