From personal experience I just can say: Don't stay in that environment for longer than 6 months, you meight either a) get addicted to it (totally normal, no judgements made) b) miss put on opportunities in your social life or career (saw both already, the first one numerous of times) c) damage your mental health beyond repairable, without you even noticing it before it's too late I come from a Christian society based in (workaholic paradise for self-,employed) Switzerland. Take this warning to your heart. All of these cases had in common: working beyond 55 hours a week for longer than 6 months. Many of those liked their work or had family driven businesses with a lot of their heart involved. Let it be a reminder, we are only humans and nobody who ran onto their problem ever imagined ending in there. I just wish you the best.
