do, by doing...

As a teenager in 4-H clubs, I learned the motto learn to do by doing. I could alter this motto to say learn to think by doing. Much has been said about the power of thought to effect action; however, the flip side of this equation is that action also influences thought. Take the action of eating salt, fat, and sugar, which stimulates the pleasure centers of the brain, starting a chain reaction of thinking that influences the brain to think of salt, fat, and sugar. The more you eat, the more your brain thinks about eating and tells you to go for these substances. Conversely, eating nutritious food influences the brain to stimulate thoughts of eating nutritious food. The more you eat nutritious food, the more you want nutritious food, and thoughts of junk food gradually fade away. Not only are you what you eat, but what you eat creates what you think, which further influences what you eat.
