I can't be the only person who feels like they're delusional for not working overtime, right?

I (51m) am a software engineer. I work for a large consulting company. <br><br>I don't work outside of my eight hours a day. I do a decent job. It's not perfect, but it works, it's good enough, and my co-workers like me. Our job is just to integrate third-party software and rebrand it. <br><br>My co-workers regularly work out of hours. Sometimes I'm forced to do a tiny bit of overtime if something needs to be done immediately, but other than that, I always shut everything down when I'm done with my eight hours. <br><br>I'm getting more and more afraid because everyone around me always talks about all their overtime and says how they have to put in 60 or 50 hours a week to get their work done and keep up with their projects. <br><br>Am I seriously the only person who all these jobs feel realistically doable and sustainable at 40 hours a week? Or am I going to be fired or passed over for a promotion because I work "normal" hours?
