This 100%. I got burned out by the classic case of working at a startup from pre-seed round. After two or three years or so of working virtually every single day, including between leisure activities on “days off” and almost always “on call” replying to emails and DMs, I just stopped. I didn’t reply at absurd hours, even if I knew the answer or had something to say. I didn’t spend hours outside of work thinking about work anymore.

Over time, I started putting more time into properly decompressing from work at the end of the day so I didn’t feel stressed about the next day.

I get burned out from time to time still, but it’s much more “in the moment” burn out vs systemic burn out.
