Take any hundred people who want to rap and follow them for 10 years. Of those hundred: only 1 will be a top notch MC; 4 will be making a living from it; 15 will record albums that don't sell, 36 will be laughed at by their friends, and 44 will never get the balls to perform live, let alone record an album or enter a battle. That�s 5% successful, 95% unsuccessful.
What separates the 95% from the 5%? The 95% didn�t train.
