Treat each job as a university course you're being paid for. Most jobs, if you fuck up, nobody dies. In other words, don't kill yourself over it, it is not war.

Treat each job as a university course you're being paid for. Most jobs, if you fuck up, nobody dies. In other words, don't kill yourself over it, it is not war. You're there to learn the material and get a passing grade. And once you are finished learning, it is time to move on. Ask yourself regularly: What did I learn today? When day after day for several weeks your answer is "nothing", it is time to move on. Make one or two close friends, and make friends with everyone else.
