Then why stay? Why waste quality of life for a startup lottery ticket that data has repeatedly shown will most likely fail? Being a non-profitable early stage startup is no excuse to run the place like a slave ship.
I think this is an interesting comment. Enjoyment of work is a large contributor to my "quality of life". And working at a startup provides interesting and unique work.
I find it interesting that everyone always assumes that working more hours means less quality of life. I thoroughly enjoy my job, so spending more time doing it does not detract from anything.
Do you have a significant ownership stake in the company? If not, then why the fuck are you killing yourself working all this free overtime for nothing?
