That’s not the definition of burnout, that’s just being uninspired. Burnout is a combination of cynicism, depression, and lethargy that can come from failing to maintain a healthy life/work balance. (I’ve experienced burnout at a job I loved.)
Can you go into more detail on your experience with burnout? I’d like to understand how it came about for you.
I don't have time right now but I've been thinking about writing it all down once I've had a chance to reset. I'll post it in here if you're interested.
