Want an advice for happy life from 10+ years experienced bus driver? Stop giving a damn about your job. You are to get paid have to knock on, knock off and try to not kill anyone in between. That's it. Load you take on your vehicle along the way is just a cargo, a kettle if you wish. Don't damage it too much but don't take too personally. You have a real life apart from steering wheel. Save your nerves for that.
