15 Become a DJ It goes without saying that you need a deep love of music and an extensive collection of tunes before you can even consider DJing, but as much of the work is at evenings and weekends, it could make a perfect side business. Be ready to cater for a range of crowds and musical preferences, not just your passion. Learn the ropes by concentrating first on weddings and birthday parties or by doing roadie work for an established DJ, which will gain you useful contacts.
