Most young DJs have ADD - or the DJ equivalent of ADD. They are constantly fidgeting with every moving knob, button and dial in the DJ booth, switching tracks every minutes (or less) and basically making their set all about THEM and not about the vibe. As you grow, you start to develop awareness of when to apply effects, loops etc - and when to LET A SONG PLAY.
I use Traktor and am constantly adding elements to the mix using 8 sample decks, effects, loops etc. But only things that enhance and add something positive to the vibe. If you are playing good music, you shouldn't need to switching things up every 30 seconds.
Build a vibe, create a vibe, cultivate a vibe - and learn to let it grow and mature. Like a fruit, if you pick it too soon (it will be sour and unsatisfying.)
