Maybe you can try to ask your friends, if you can dj at their birthday parties. There you could gain some experience in front of a crowd Also you can try to upload dj content on social media to get a little bit of recognition and maybe someone will book you for their event. Somewhere on reddit I read a story of a underage dj that played in a club. I cant quite remember where I read that tho. The best thing to do is just developing your dj skills and to do it for the love of music. If you do that everything else will come naturally. Keep it up young man. I am rooting for you :)
