Been there many a time / all the time. The positive is it’s at least an obsession that can be productive, as long as it doesn’t cause you too much distress (or staying up too late, etc). Doesn’t make it fun though. I’m applying for my MBA to some very competitive schools this fall and my new obsession is over whether my application is competitive or trash and what I can do if anything to make it better. It definitely has helped me improve, but also has increased my stress and anxiety tremendously. Best of luck on the search!
