I agree with this wholeheartedly, it's harder to notice this in a field you are a professional in, but what really opened my eyes was noticing how often friction kept me from making mistakes in hobbyist metalworking/woodworking projects. More than once I've either made or didn't make mistakes based entirely on if the tool I "needed" for the next step was in arms reach or a walk across the garage and a search through multiple toolboxes.
