This question is for anybody and everybody at HubPages who is a DJ, a music mixer (be it House, electronica, Lounge, Chill Out, Downbeat, Trance, Jazz Fusion, or Hip Hop). It's a multi-part question. 1) What drew you to this field and how old were you when you found your "calling," if you will? 2) How long did it take for you to get good, and how soon after that did you get your first job? 3)What do you need to get started (the amount of the mimimally required initial outlay and kind of equipment -- the basic "starter" package)? 4)Does one take classes these days (are there classes) or does one have to teach himself or herself?
