Networking in mindset, your network is your net worth. Meeting, connect with as many people as you possibly can. Many of my successes came from being a go getter, and going to the clubs I wanted to work out and introducing myself to the right people and telling them that I want to play here. Things don't just fall from the sky, you really have to go and get done. And if you really want to be DJ, and believe that this is your dream, and you better pursue it, go all in invest all your time and energy to make this happen. And this can be applied to anyone in any business, be an opportunist.
Most successful people's lucky breaks, so to speak, have come from just taking action on an opportunity that presented itself time and time again over and over again. An American DJ friend of mine that I met in Europe had the chance to spin out Tomorrowland because he met lost frequencies and gave him some music. He's a Belgian by native and had his own stage at the festival. So you never know what can happen.
