Becoming an EDM DJ totally depends on the way you perceive music, and on your perception of success. No success will come to you overnight, and trust me that you will never have it easy! Hence, becoming a great EDM DJ is all about your attitude and the amount of effort that you put into learning, practice, and production.
Apart from that, it also depends on the level of patience you have until you make it big. Because certainly, most EDM artists have not had an overnight success with ease. Each one of them had put in great energy and dedication.
