Not to be a grammar Nazi, but I find your misspelling of “roles” to be hilarious.

I’d say your assessment is pretty accurate. Right out of college I took time off before looking for a career and got a job driving a van for the Holiday Inn, which was awesome.

My work week was 32 hours and I have to say that was a pretty sweet spot for full time.

I think you should give more information about the relationship between productivity and hours worked. It is too difficult to understand your position.

Saying the relationship is not linear does not tell us what you think the relationship is.
