There's presumably a reason you entered the program. Remind yourself of this often. The end goal is what you are looking towards. Yes, everyone else is too, but whether they are or not, that shouldn't be your problem or your concern. Your concern is reaching your end goal. Focus on that, and how your hard work will be worth it at the end. By your end goal, I don't mean finishing the program, but rather what you intend on doing with the knowledge after you are done with it.
