Making it in the music industry is not something you can just gain because you want to or because you have trained very hard for it. Some people train very hard because they really want it, but in the end, they also fail. Making it in the music industry is just the right combination of some qualities and skills and a little luck.
First and foremost, you should have the talent and practice that talent. Of course, it would be a lot help if your parents have brought you to expensive schools or lessons just to have that singing skills or guitar, piano, violin skills, or whatever musical instrument you play, be developed. However, even if you are constantly trained and your parents have paid so much just for you to reach that highest note, but you just do not have the capacity to do so (whatever reason there might be), then you will be learning some, but you will be as good as others. It is also important that you have the skills, the natural, inborn kind of skills. In short, you should also have the potential. You might be able to reach that highest note, but the quality of your voice is just average or just not for singing. This potential, when developed, can turn into the birth of star in the music scene. However, talent alone would not also work in the long run. Talent must be paired with constant practice and studying. Nature and nurture should work hand in hand.
Another thing to do is to get yourself noticed. Even simple performances in weddings can get you recognized and actually paid. Do not underestimate these small events (compared to concerts or television reality shows). These give you opportunities to benefit financially from your talent, practice and develop your performance, and could give you some exposure. You will never know if anyone on that wedding might know someone who works in the music industry or a talent scout is there looking for a new talent. However, do not just keep on hoping that you will be bumping to someone who is a talent scout or someone who is in the music industry, who could help you step in the ladder, too. You can increase your exposure by performing in events like weddings or in local events. You can also send tapes to record companies or find ways to meet people in the music industry.
