> when using my brain, my subconscious can only do very simple things for me and it's very difficult to teach it anything new. That's fair. I'll often forget the details or maybe the abstraction isn't good enough, or abstracts the wrong thing. I often have to switch layers, pick up some critical info, and keep that in context when working above. Sometimes it happens often -- forgetting piece A to work on piece B, then forgetting piece B to remember piece A, then having to remember all the intricacies. I stopped trying. I just write unit tests for the layers and details. It also helps me to keep things simple -- if the unit test is too complicated at a lower layer, then the upper layers are going to be even more complicated. So simplifying that layer is certainly necessary.
