Swimming

Okay kid here's your new life:

You've got a nickname of being the Shark in school for being adept in the water, not being able to sit still, and having predatory vision. You find something you want, you seek it out and you get it. People who don't know you get the idea that you're willing to do anything to get your way, but that isn't the whole truth. School is a secondary concern for you; just as long as you keep your grades good enough to be on the team and hopefully get a scholarship at a nearby university. For now, your goal seems mostly to enjoy the days you have before you have to be responsible for yourself.
