I’ll go first: “You have to have children when you’re young,” told to me when I was in my late 20s, with no desire to ever have kids, and no means to support them, by someone divorced multiple times with at least one adult child who does not speak to them.
Also: Responding to “How do I deal with this problem?” questions with “Oh, don’t worry about it, it’s enough that you’re even thinking about it!”
“Do something that you love and you’ll never work a day in your life.”
Bullshit. I worked in the video game industry in a field I’m very passionate about with great people who were all talented. But the industry burned me out and almost killed my passion for games as a hobby with the endless unpaid overtime, constant crunch and deadlines, fairly low wage and all that investment was rewarded by eventually being let go along with all the less senior staff because our studio was bought out and the parent company told to cut expenses.
Don’t work for the video game industry, people. Make indie games by all means. But stay clear of the big names.
I have always hated that advice. While exceptions exist, there is no faster way to burn yourself out on something you love than making a career out of it. I generally do like my work (IT) now, but a lot if that is because I actively try to not even look in the direction of a computer when I am not in the office. I probably consume less tech/IT industry news now than I did before I worked in the field.
