Reply to Well that's just disheartening

Hey guys, just read an article on the djtt blog here and I'm not going to go on a rant or anything but in the article it said you basically have to give up any full time career you're pursuing or have and use all that time to dj and produce music. I'm just seeing what you guys believe because I'm 20 years old right now and have been producing music for about 2 to 3 years and have listened to EDM since I discovered Ferry Corsten on Itunes when I was 12 years old and now and I'm finally getting to a point where I'm proud of what I'm making and am starting to get noticed. I've always had aspirations of being a professional dj/producer but I'm not going to give up my career path that I'm guaranteed to make a living on to chase something that you have a very slim chance of making it at unless you give up everything else in your life for it. I just wanted to know if anyone out there is or was in the same situation as me and has made it without throwing their life away for it. I would still like to pursue my dreams but I'd also like to have a plan b. thoughts, comments, questions are all welcome
