Non-artists tend not to realise how much labor is entailed by drawing, I think because they compare it to other desk jobs. But the difference of focus and physical activity between art and other desk jobs is staggering. I used to work remotely for an ad agency... https://twitter.com/reimenayee/status/1295777377050488833

There was a team of on-site art directors (ADs) who designed the advertisements, and a team of remote-working illustrators who drew the final designs. One time, I visited the office, and one of the other illustrators happened to be working there alongside the ADs.

The ADs were chatting, moving about, joking around, sipping their coffees, etc. The illustrator had her head down, staring at her Wacom, unbroken focus, moving like a sewing machine. The contrast was striking.

It's not that the ADs were lazy; they were doing their jobs. But their jobs didn't require nearly as much dexterity, speed, and laser-focus. I realised this was why I was always shattered by the day's end, while the ADs were always calling with extra requests like it was nothing.

For them, extra work WAS nothing, in the sense that it was just another relaxing half hour of moderate activity. (This also describes my routine back when I did secretarial work in my pre-art days.) But for us illustrators, every minute at the desk was like driving Formula One.

So if you draw for a living, don't let folks shame you for working "behind a desk," as though sitting in an air-conditioned room will magically prevent stress, eyestrain, repetitive motion injuries, and other pitfalls that threaten artists more than they do other desk-workers.
