Well, you need to know that being a magician is not easy because it is show-business. There are two parts to that - performance and business. If you can`t do both, you won't make it.
So for business, some education in this area will go a long ways. It takes an entrepreneur to be able to be successful in running your own business (which is exactly what a magician does). It takes drive, initiative, creativity, passion, smarts, ambition, and common sense. Financial management is an absolute must. You need to be able to take care of your taxes, pay into health care plans, performers insurance, all on top of all the other bills one needs to pay.
And much much more.
For some ideas on the business side of magic, both Jim Snack's course and Lou Serrano's course are highly recommended.
For showmanship, that comes with dedication, and growth in this area. Hands down, I believe that Graduate schooling is one of the most incredible ways to help in this area. Get a degree in theatre. It will change you. Plus after you get a degree, it can serve as a back up to get other jobs (even working at a university for example, you need a degree in anything for most jobs). But I feel, especially if you are not a natural entertainer (and don't fool yourself), then taking a degree in the arts will empower you to succeed. --and keep in mind that you will also have to take classes in other disciplines than drama, and these classes will also empower you. A higher education shows. You will be more intelligent for it. It will even come across in the way you talk.
I don't know you, but if you are dedicated to this, then that would be the direction I would recommend going. Perhaps majoring in drama and minoring in business. But absolutely go to university/collage.
Good luck to you!
