Throughout my life, I have always possessed a deep fascination and passion for strategy games, such as chess or risk. However, it was not until I was thirteen did I discover Magic the Gathering, a highly complex strategy game somewhere between chess and poker. Magic mainly tests your ability to do three things; observe your opponent's body language; apply risk-payoff theory; and analyze a system multiple ways, then exploit its weaknesses. Though young, I quickly learned and designed my own strategies, competing with thousands of players, most of whom more than twice my age. Little more than a year later, when I was fourteen, I won the Star City Games $5,000 Open Tournament, becoming the youngest player ever to win a professional tournament. Since then I have won many tournaments and ranked in the top one thousand players out of nearly six million worldwide. More important than money however, Magic taught me to observe and analyze critically on both a micro and macro level.
