So I have always had such a nice (some would say epic) work-life balance as far as "hours" and "availability" go. After a (forced) break from work, and exploring health related help professionally, I came to know I was clearly burnt out. I was told high number of "hours" working or "visible or quantifiable work load" don't necessarily have to be present for a burn out. There are other factors at work which cause stress/etc and they are often more insidious than the typical "load" (not to reduce the ill effect of the typical load^). And were those signs abundant in my life and work!

It was quite shocking. I always used to think that with my kind of work-life balance at least burn out was never going to be a problem.

^ It was added by them - those typical load/etc almost always cause mental health damage so I should not consider them okay all.
