The success of failure is a popular topic these days, but there’s a more subtle version of this, more persistent, and relentless.  It’s how a photographer learns to take those amazing photos or a teacher figures out how to deal with tough situations. It happens bit by bit, small increments of change, and over time something very difficult begins to look simple. Every experience is an opportunity to adjust and fine tune.  Little things that didn’t quite work out become grist for the mill.
