You can start making youtube videos in the subject you are passionate about. Not sure the type of artistry you have, assuming you have some kind of a singing or a music skill, start making youtube videos on the subject you are most passionate about. Then share that with your audience through your Facebook, Twitter, Blogs etc. Have some kind of continuity between one video and another so people will subscribe to your youtube channel and come back for more. The more videos you have the more attention you get. Then may be a music producer will come to you asking you to make a music video.
Also check out my book Puga Sankara's Supply Chain Blog - that is a must read before spending Hundreds & Thousands of $$$ on your MBA or Masters Degree to get the best ROI or before starting your Entrepreneurial journey.
