This is a really helpful way to think about natural numbers. I like to remind myself that we can gain efficiency through abstraction, but true, intuitive understanding comes through concretization/deconstruction. Interestingly enough, I use round stones to represent ideas when I meditate. As the ideas come to me, I pick them up, examine them, and weigh them. If the idea is pressing, I delve into it and think it through. If not, I put the stone down and wait until my mind picks up the next. Mental stones: some of modern life's most useful tools :)
