This is a very naive take. There are people who live paycheck to paycheck with the threat of homelessness. They can't just "accept" they have burnout, they have to work as if they don't just like any other person. I myself had a brutal burnout recently (hopefully recovering now slowly) but it was very difficult because I work on a visa and I can't afford to take a break or PTO etc. Yes I "accepted" that I'm burned out in an academic manner but almost everything my therapist offered was out of question. In that sense of course "I can't be burned out because I have too much to do." I still have to work every day, churn the churn, hustle the hustle, write the performance review forms, avoid PIPs, otherwise I'm deported in a matter of months. Managers expect exponential return every quarter!
