 Not to have your thoughts guided and steered and pointed this direction and that by algorithms. No, when you do nothing, your mind directs itself. And thinking is, it turns out, a lot of fun. You should try it every once in a while. And you should be able to entertain yourself with your own thoughts. In fact, that's why I relish being on a plane when I have nothing to do, because it gives me that chance to do so much while I'm doing nothing. There's so much thinking that I get to do.
