Writing and Exercise

A long while, I have struggled to write abundantly and skillfully, and for decent lengths of time, because, I think, I've not listened carefully to the way my language sounds, and also because I've been getting so little exercise.

I think that, if I exercised more, my brain would function better, and I would have more self-discipline to write. I would also be able to read my Bible more, pray more, and meditate on God more. Probably then I would start to obey God's Law better. However, I do not understand why the Bible says, "Bodily exercise profitteth little."

Since I lack self-discipline, I've not been writing much at all. In the past two or three years I have written almost nothing except forum posts. I've been writing very infrequently. I have also been hearing voice saying that I am illiterate. The voices sound very stupid. They are also saying I am slow. I do not understand why they say I am slow when I read very fast and understand very fast except when reading sophisticated language. My problem is simply retention. It's not comprehension. As for the verse, I know that it is saying physical exercise provides little benefit, but if it leads to godliness, how is that a small benefit?

When I wrote the second paragraph, I stopped attending to how my language sounded. I struggle with laziness and cognitive inability. I think this is simply due to lack of optimal nutrition and mostly exercise.
