Many fly around in my mind. To harness them, I wrap my fingers around a pen. If at the computer, the keyboard is a magnet pulling my fingertips to it. At first there is a sputter. Then all the cylinders fire. At times my mind passes the speed of my tapping. So there is some backtracking. Getting it down I’ve read is the most important. Edit later. I put as much as I can down, emptying my head as often as possible. Sometimes it still doesn’t seem to be enough.
