I doubt many ppl in this thread have worked this many hours but I've worked 60+ hours for 5 years. I had an office job and a part time job, nights, in my mid 20s. It was literally the worst experience I ever had.

I was in pain all the time, I ate twice a day, sleep 2hrs in the morning/2 in the evening and had memory gaps. I would forget what I did certain days shyt like sleeping with a Bank officer at her spot, at least thats what she told me. I kept a notepad with me because it started getting bad.
I'm a natural loner so it didn't bother me that much but I rarely saw my family in this time period. I lost touch with all of my friends. The only thing I was worried bout was making money...I couldn't even enjoy the attention I was getting from women or spend the money I was making because I didn't have time. I even had to schedule my shyts.

I feel like I wasted my post college 20s. And it becomes harder to build solid relationships as you get older. If yall don't care about your mental/physcial health, personal relationships or living life, work them 60+ hours.
I've seen ppl have mental breakdowns for far less but maybe you're an emotionally distance loner like me who can handle this type of stress
