Tennis is the fastest growing sport in the world right now. Year after year the sale of tennis equipment such as tennis balls, tennis racquets, ball machines, bags, clothes, etc. are sky rocketing. Every day, no matter how many times you walk past a tennis court you will see more and more new people just starting and learning how to play the game. When it comes to playing the game for the first time, it becomes fun and addicting, but when you hit the ball over the net with the sweet sound of a beautiful pop off the racquet for the first time, it becomes a drug. Tennis isn't a sport of competition, it is a sport of love and in tennis the number zero is also called "love". So no matter how much you understand the game or how much experience you have playing the game, keep in mind that "Tennis starts with love".
