My first full time job job out in the wild was as a retail manager. I was expected to work 54 hours and during the Christmas season I basically was at the store if it was open, period. My record at that job was 80 hours in one week.
That was between the ages of 21 to 24. By the time I was 23 I was already completely burned out. Unable to enjoy life, making next to no money to boot. Seemed like every year there was some excuse why my bonus sucked, even though I ran the most profitable store, by percentage and dollars, in the entire region. It culminated in my regional manager forcing my district manager to demote me to another store because I didn't run the sales gain numbers he thought I should... Even though my store was both profitable and I ran sales gains every month. They handed my clean, well sorted store to a god damn thief who they ended up pressing charges against within the next year. But hey, he ran big sales gain numbers. The regional manager was an absolute prick and he later got fired for stealing carpet...
The company is out of business now and good riddance.
40 hours is more than enough time to devote to making a paycheck. Honestly, 32 hours is enough too, especially since these employers expect you to commute. Concepts like "Rush Hour" only exist because of the insanity of making a buck.
I left retail to enter the IT industry, which can have some crazy hours too. I did my stint being on call and doing changes at 3am on Sunday mornings, working outages that lasted for days. Those days are behind me too. Today I work from home and my boss only cares if my work is done and that I'm available to answer emails.
My girlfriend in college, who was really my first real love. I move to a bigger city for a job, we get engaged and make plans for her to move to the city then... She just ghosts me.
She calls me at work out of the blue two years later. Turned out she met some guy with a nicer car than me... However, apparently having a nice car does not equate to being treated well... Which I did treat her well.
When she called me, I was in the middle of job burn out, almost no social life and just really not in the mood for bullshit. So no, we never got back together and I'm glad.
