Two ideas help me with it.

One, the idea of what works. Blaming other people rarely gives any obvious route for things getting better since it's treated as this insurmountable wall. That person isn't making it hard for you all on their own, they're just part of a situation that's hard for you. You need hope as part of staying motivated, and part of that hope is seeing what actions you can take to improve it.

Two, you're not an authority. It's easy to see a lot of things you grew up valuing as how it should be for everyone, when really a lot of the time it's different life styles and abilities. Even if you can't understand the alternative, you have to accept that everyone has their own way of living, their own values. Maybe it's a job and you go above and beyond but feel handicapped by a coworker that just does the minimum. Maybe that's all they can do, maybe they view the job as hostile and don't want it to take up more energy than it needs, maybe they're fighting for more resources so you don't have to go above and beyond just to get things done, maybe they work hard on something you don't get to see much of, or who knows. It sucks and that's valid, but they're not doing something wrong there, they're making a choice for their self.
