traction.

When you run in the snow, you realize pretty quickly how much harder it is to find traction. (Incredibly obvious.)

But, what’s more interesting is that while running in the snow and finding a patch of asphalt for a moment, how good that traction feels. In fact, it almost seems as though the ground is propelling you… pushing you forward with each step, compared to the lack of it in the snow.

More interesting is that traction requires - is almost a form of - friction.

So… pulling this out a little. Running on the snow reminded me, again, that in order of life to really get moving with some force, it’s helpful to have a little friction in it. And sometimes you most realize that when you have no friction.
