Life isn’t fair. I said. It’s taken me a while to get that. It’s always going to disappoint you in some way or another. You’ll make plans, and it’ll push you in another direction. You will love people, and they’ll be taken away no matter how hard you fight to keep them. You’ll try for something and won’t get it. You don’t have to find meaning in it; you don’t have to try to change things. You just have to accept the things that are out of your hands and try to take care of yourself. That’s your job.
