Haha, I may be new here, but I am certainly not the youngest.
I am 42 (but look fab for it 🙂 )
I do think you can use your age to your advantage!
I used to DJ at clubs many years ago and I would say if you are really nervous to the point of being uncomfortable you are not quite ready. Though it was easier to make mistakes on 1210s than with digital TBH (another debate for another thread).
I think I could play clubs now and I have only had the gear a few weeks, but I think that is mainly because I learned to Dj a long time ago and this is just a new tool set.
Good luck!
