It’s not the size of the dog in the fight, its the size of the fight in the dog.
I try to be competitive in everything I do. If I’m on a run, I try to be the first one in. If I’m in the classroom, I try for the best grade in the class. (If I get up to sharpen a pencil, I try and make it the sharpest pencil in the room.) Granted, I’ll never be the best at everything, but that doesn’t mean I can’t be the best at something. I just wont quit trying to get there!
