Another thing that can cause a problem is having to stop work on something for an extended period, then come back to it. I learned, working for an architect, to always take notes on what I was working on. I am plenty smart enough to keep the details for a large remodeling job in my head while doing the drawings, but recreating them after being diverted to a different job for 6 months was a royal pain. So I learned to make notes of every idea I had, rather than just adding it to the next revision of the drawing. And the more literal point ESR made about disciplined study skills has also bitten me several times.
