It reminds me of the Grazing Principle, from _Beyond Success and Failure_ (Beecher):
"The Grazing Principle is at the root of all great discoveries, and it is the path of our enlightenment. It might be called 'horse sense', since every horse is a fine exponent of the principle. If you turn him loose on a roadside, he begins to graze immediately. He sees a clump of grass and starts to eat. While he is nibbling this clump, he sees another not more than a half-step away. He reaches for it, and as he is cropping it, his eye falls on yet another clump just a short step ahead of him. And that is all he does all day! But by nightfall, he is miles away from where he started. Without any thought of 'getting ahead in life', he has moved into new grazing areas continuously. And most of all, he has enjoyed every moment of the process. No fuss or anxiety. No need for rewards or recognition outside himself."
