I was watching something and it made me realize something, that in order to be really great at what you love to do, you have to obsess over it, love it, hate it, want to do nothing but it, and at the end of the day when you go to sleep still thinking about it. So what I'm trying to say is, in order to be really GREAT at something, you have to lose everything else, so you have to weigh it. Say for example your a doctor, what is more important to you, going home at 5 so you can go spend time with your family, or friends, or staying at the hospital for 60 hours straight making sure every patient you have is okay, and that it's going to stay that way. Think about it.
