I have a friend who have ventured in the sound system business. At first he only collects stuff for his personal use. I remember him telling me that he likes to have some top logic studio. Little by little he was able to come up with the necessary and start renting his stuff. He then undergo some training and kept on studying. Now, he seems to be able to established himself since some big companies have already been acquiring his services for their music for every events. I am so happy that somehow he had found his niche in the music business. I hope one day we can also see what business we are going to pursue.
