I started rapping before anybody had ever bought a car from it. It was truly about the art form and the culture, more so than now, where it's a successful way to make money. Back then you had to be doing it because you liked it.
Money has never made man happy, nor will it, there is nothing in its nature to produce happiness. The more of it one has the more one wants.
Rappers should just be able to perform what they create and satisfy the people that like and love them.
