You don’t know. At the beginning, you have no idea. But you have to start in, because it could turn out to be a good one. And you won’t really know until around the middle, when you might as well finish up anyway. It takes time. Once you’ve picked one, seeing it all the way through takes time. So you’ve only got so many shots. You can’t start in on every one, and there’s the trouble. You have to decide, standing right where you are. You might find a pair of binoculars and look out ahead as far as you can. These are the planners. Or you might say, well heck, I’ll spend as much time sitting here looking as I would if I just ran on down the road a little bit. These are the runners. Some are a combination. They’ll run a little ways and then get out their binoculars. But either way, you’ve got to run the whole race at some point or another. Some run the race a few times. Running is one thing. Picking the right track is another.
