There's nothing inherently unnatural about taking a bottom up approach to solving problems. Sometimes, knowing you're going to need a particular tool and doing that first makes sense. I think of it like the cooking technique Mise en place [1], where you lay out all the ingredients before you start cooking. Neither bottom up, nor top down, is always the most natural way to attack a problem. Sometimes you can attack a problem from both sides at once. http://en.m.wikipedia.org/wiki/Mise_en_place http://en.m.wikipedia.org/wiki/Mise_en_place
