Im 27 and still DJing. Its allowing me to put alot of extra money aside for purchasing a home. I have a very good fulltime job, but the extra cash DJing really helps things out. Besides, I rarely drink and am not much into the bar scene, so its not like im missing much having to work weekend nights.
I was a DJ for 8 years. From when I was 19 till I was 27. It was great side money and It wasn't even like work. it was also a great little sub culture, I knew all the other dj's around, NEVER had to wait in line or pay to get in a club, and when you were at a different club you could just chill in the booth, snort some lines, and get away from all the animals packed in like sardines.
