Around 6th grade I decided to take up roller hockey, but was pretty bummed out when I tried to learn how to move around in rollerskates. I couldn't make much progress for the life of me, until one day, I stumbled across the solid advice of learning to skate _with_ a hockey stick while chasing a tennis ball. I was skating as fluid as a twelve year old could within one week. I had always attributed the accelerated learning to that tennis ball and the subsequent "desire" to chase after it out of necessity, but now I see that focusing on the tennis ball was helpful because it muted my prefrontal cortex activity. Neato.
