So, the cool things about Magic is fantasization and competition. The card game is a low cost substitute for fantasy and competition in real life, and it's semi-socially acceptable, so there are others who will support it. Whether you prefer women or men, there are mostly men who play it. I'm in my thirties, and friends of mine played magic when I was in high school. Most of those friends grew up to be computer code programmers, and work with computers in general. A few of them do websites, graphic design, etc.
Another cool thing about magic is the artwork. Some of the cards have really cool art on them. The stories and fantasization are kind of clever. There are a handful of successful fiction writers.
It might be the case that one above the rest of these things starts to appeal to you. There are a lot of cool aspects to the Magic game, but I found most of my friends just prefered to socialize with the alternative crowd. Maybe it's different these days, but too much socialization with the alternative crowd might make somebody miss the point of society.
So, if one of those aspects appeals to you, or you like computers, start thinking about pursuing that as an interest. Chicks, and guys I suppose, dig guys with an interest, and if you start getting good at something now it will pay off when you are an adult. There is a greater probability of being a succesful IT pro than a successful fantasy author, so factor that in.
