So if people are going to be doing all this thinking, they’re most often doing their thinking with their heads, at least according to idiom. Sometimes they’ll do the thinking with their hearts. Some people will go a littler farther and do their thinking with their bellies. There are one or two other organs that get to do thinking sometimes, but there’s still a whole universe of body parts that don’t seem to get to do any thinking done. When have you met someone who’s noted for doing his thinking with his wrist, and is it for anything besides grasping onto stuff such as jars and bolt cutters? Or how about doing his thinking with his knees, which probably marks a person who does a lot less squatting than the rest of us? Does anyone think with their fingernails? If they do, is it in favor of itching, so fingernails get to be useful for scratching purposes, or against itching so as to get a break?
We all come up with ideas we can’t really use, because there’s only so many things we can do any given day and clearly the inspiration “sponge or brain” isn’t going to help most of them. But just because you don’t have any use for an idea right now doesn’t mean you’re never going to have one. Things might open up.
What you need is to have some kind of depository for your abandoned ideas, where your abandoned ideas can settle and compost and go about making long-distance calls to one another. In fact, having such a depository is such an obviously good idea that you have had it, but you were too busy to make one. So the abandoned-ideas depository idea was itself abandoned, which is great because it fit right into the depository once you thought of it, only now, there’s no way to get it out, because right outside the abandoned-ideas depository is still inside the abandoned-ideas depository; ask any topologist for an explanation. I’m afraid even this note won’t help. By the time you’re done reading this, you’ll have no idea what I was going on about. I had one but I don’t know what it was.
