Once you start focusing on what's within your control - your attitude, your work ethic, the way you treat people, and the way you show up everyday, you become a lot more productive and focused, because you aren't concerned with office drama as you're trying to finish a report on deadline. You aren't concerned with who you might be competing against for a new job, and instead you're able to exert all your energy into making yourself better, allowing for the situation to play out as it may — you can't control the outcome, only the the effort you put in.
