My peers are publishing high impact papers and getting awards or offers while I am struggling to write a decent paper. What should I do differently?
If you're working 80+ hours a week, it's possible that that's getting in the way of you taking time to get enough sleep, and/or to maintain a healthy diet, and/or to get a decent amount of exercise, and that in turn is adversely affecting your cognitive function and impeding your ability to produce your best work.  It might be worth trying taking your foot off the pedal a bit.
