I suspect if you're commenting in this thread, you'd probably enjoy it.
Anyway, the one thing that seems to always be a consistent theme in discussions of burnout, is work. I've not yet seem a conversation on burnout where an employment scenario is not brought up.
One of the chapters in Lost Connections talks about meaningful work, and how a reduction or elimination of personally fulfilling work, can lead to a depression, as can a few other things.
I can't help but feel at this stage after dealing with a long running depression, that our relationships with work are probably broken, and we've all been sold a lie.
My issue with the term "burnout" is that it feels like it's loading the topic to be a personal issue (which it technically is), when in reality, it's a reaction to a bad external stimuli.
I'd write more, but I feel like I'm waffling, I'm happy to discuss more if people want to chat about it.
