Like Geo, my background is in art and graphic design. When it came time to put food on the table for a wife and family I realized I wasn’t going to be where I needed to be financially unless I took a divergent path. For me that was mechanical design and industrial art.
That field of art is much more rigid, and all about conformity to industry norms. This was in the days before CAD systems were common, pretty much all technical drawings were still done by hand at a drafting table with a parallel straight edge and triangles or if you were lucky, a mechanical arm.
Object lines had to be three sizes wider than dimension lines, hand printed text was all caps and dead vertical, object drawings with multiple views and notes had to be laid out properly for the drawing size being used, vellum, mylar or other drawing paper had to be a match for the rapidagraph pen or mechanical pencil being used and even pencil lead types and eraser types were dictated.
To Geo’s point, my fist drafting boss drilled into my and everyone else’s head in the drafting pool - that the goal ISN’T perfection. His position was that you’ll never reach perfection, it’s relative, and trying to get there will cost the company unnecessary time and money. Besides, they hire drafting checkers that get paid to find something wrong with your drawing, and they always do.
His expectation that stuck with me throughout my career and still plays a major role in my creative endeavors was simple but powerful. All he wanted was for each of his drafter/designers to “Autograph their work with Excellence”. To this day, I still follow that advice.
I’m my own worst critic, if I create something that has a flaw that I spot, no matter how small or insignificant, I pretty much go all OCD over it until it’s corrected. I’m happy when it’s excellent. Is it perfect, that all depends on who you ask, and really doesn’t weigh in as heavily to me as just putting out excellent work.
