Doozer,

If you think about it, a project like that with many steps that get completed along the way, is very therapeutic.

That is what I would call a macro job. It uses macro thinking chunks, vs a micro job where one needs to make intense and precise fine decisions.

Even when there are needs for precise decisions, they are usually single step decisions vs complex multi-step decisions with multiple variables to juggle. This ability to do what would appear to be a complex job by breaking it down into much simpler decisions and tasks is much better for the struggling brain.

When I get in a situation where I have that complex task or decision to make, I try to step back and break it down as much as possible. My brain handles it much better. Even writing down a matrix of the variables can be a big help. It prevents the need to do mental juggling.
