Burn-out is real and it hurts

Reading this post, Only Chumps Work More Than 40 Hours a Week, on Medium.com, it reminded me of what I already know, but never seem to abide by. Here is the quote that summarizes the narrative the best.

If you quit work each day in the middle of doing something you enjoy, you’ll start the next day excited and motivated to do more. If you continue to work each day until you simply can’t do anymore, you’ll start the next day tired and bored. Again, I know this because I’ve been there and done that.
