sorry roq, but the best thing I've ever heard anyone say related to djing is:
don't imitate, innovate.
managers will be happy to see an eager dj who is happy to keep his music collection up to date, because doesn't this show... omg it can't be! A GOOD ATTITUDE ABOUT WHAT YOU'RE DOING!!! NO WAY!!!!!
and didn't you say a good attitude is what gets you in the door? my point stands.
