If you’re starting to DJ and don’t know anything never get gigs, you have a job, etc. My opinion is you shouldn’t go proffesional. Just take it as a hobby, and do it for fun. If you are good at it, have contacts and get gigs, go with it.
But its your life who am I to ruin your dreams?
So yeah, if you’ve done it before, go aheaad.
PD: I know It was just a question, but this kind of stuff you shouldn’t care about others opinions. You do what you want to do with your life, have some fun. 🙂
