It really depends on what particular area of the industry you want to aim for. If it's the perfomance end, you will be well aware of just how hard it is to break into anything resembling fame and fortune. If you can sing, why not join a local band and get some experience. No bands? Form one! You are going to have masses of ambition, stamina, and talent - in that order - to get anywhere, but a lot of stars are in the right place at the right time, as was Robbie Williams, so it can be done. If i can offer any more advice on specific areas, please re-post.
