"Sleights of Mind"

Here is an interesting NY Times article from which you can infer some of the difficulty one may have in describing one's own mental process. Part of the problem is that the left lobe of the brain specializes in making up explanations, but even more basic than that are "the limits of cognition and attention."

Still, it is possible to create something useful out of what we can patch together, guess at, experiment with. It is not necessary to create actual tracings of reality, only a useful map.

And in constructing such a thing you are doing something similar to making art, to begin with. But what will give your efforts the integrity it needs to be useful is working at and learning the craft.
