“Imagine yourself as a kid who wakes up after a night of heavy snowfall.  There’s a thick layer of snow on the ground, clean and without a path.  The first time you walk through this snow, you have a very wide array of choices for what path to take.  You can walk to the left, down the middle, to the right, zig zag, walk over that hill, and so on.  Not only do you have many choices of paths to take, but each one will be very difficult, because there’s a foot of snow everywhere.  Now picture walking to school the next day …the snow from the previous day is still there, but now there’s a bit of a path you created from yesterday’s walk.  You can still create a new path, but the one you created yesterday will be a bit easier.  So you take that one.  Each day, you decide to take the path already created.  This is a groove in the snow that gets easier over time, until you’re probably not going to take any other path.  Creating a new habit is a lot like that: you’re creating a groove in the snow.  At first, you can go anywhere, and it’s difficult going …but once you’ve created a groove, it’s much easier, and you don’t have to forget new paths anymore.” ~ Leo Babauta, Essential Zen Habits (Page 28)
