I do public appearances. I'm bluff, hearty, goofy. I wear loud clothes, and I read the funny bits. I occasionally get taken to task for one thing or another, and I acknowledge my fault, my flaw, my failure, and I move on.
Every day, my daddy told me the same thing. 'Once a task is just begun, never leave it till it's done. Be the labour great or small, do it well or not at all.'
Task switching is hard because we do not control what is on our mind. Despite our efforts, the original task continues to occupy our mental bandwidth. Although we can control where our time goes, we cannot fully control how our bandwidth is allocated.
