Ask HN: After working 70+ hrs a week my manager says no for promotion

I am angry at myself for being stupid. I worked for 70+ hrs a week for one year and built a new groundbreaking platform. During my recent conversation with my manager, he told me it's not enough for promotion and we should wait. I did my best to convince him. I am wondering what did I do wrong? Quite frequently I get walked over by people. Although I am good at workplace politics I am not best. I am baffled that men and women who are underperforming are going to be put for promotion. I know first hand two people who have caused delays in projects are going to be considered. All they have is probably strong connection with their managers.

How do you navigate workplace politics and getting ahead in the career? Changing job is one option but how long I can keep running from situation? Also,given the state of technical interview and irrationality to ask any irrelevant question, I don't know if I wanna go through it again anytime soon.

What do I need to do to move ahead and up in the career?
