While I try not to work overtime, especially anything excessive like 80 hours, I do enjoy parts of my job and I get paid to do it. It's a bonus to me that what I work on isn't actively destroying to world or completely useless.
There isn't really much choice and people have been doing it for a long time including my parents so I just have to assume it's part of adulthood and accept it and try not to let it hang over my head.
Unless you make a lot of money or have help, you will probably have a mortgage if you want a house.
