No, I don't think people work 70 hours because they're successful. I think they work 70 hours out of necessity and others think that makes them successful.
If I were successful then I definitely wouldn't be _working_. Yet here I am working many hours and others claim I am successful.
Get a different job. If you don't love what you're doing, why do it? I you love doing something, why not get paid for it? People can be working 70 hours a week and enjoying it. Because you associate work with being miserable doesn't mean others do.
