I arrange my code to follow a certain order, so that I can get my head back into a given module quickly. I don't remember everything; there's too much over the weeks, months, and years. But I can remember enough to find what I need to know if I structure it properly. Not unlike, you know, a Zettlekasten.

Isn't a Zettlekasten, structured so you can easily go back to a note easily?
