My biggest challenge in following that suggestion is when I am working on one circuit, and in the middle of sorting out the one, I run across a problem with something else.
It's hard to NOT just go after that new problem you just found. (Then lose track of what you were doing, or forget to finish it.)
I suggest you do what I HAVE started doing. Take a pen and paper out there with you.
When you run across another problem, write it down.
When you have other thoughts, about what the real problem might be... write them down.
FINISH the one circuit. Then you can always go back to your notes, and choose another circuit or problem.
