I’m “guilty” of indulging in the notion of burnout. It has occurred to me that it’s laughable, in a way. Maciej Ceglowski of Pinboard explains:
Avoiding burnout is difficult to write about, because the basic premise is obnoxious. Burnout is a rich man’s game. Rice farmers don’t get burned out and spend long afternoons thinking about whether to switch to sorghum. Most people don’t have the luxury of thinking about their lives in those terms. But at the rarefied socioeconomic heights of computerland, it’s true that if you run a popular project by yourself for a long time, there’s a high risk that it will wear you out.
The whole article is fantastic: clear, candid, and mature writing about running a tech business that will interest and inspire nearly anyone interested in that, and quite a few others besides.
