Sky_lark is right. Start small. Once you've achieved a goal, raise the bar and work towards the new goal. Everything is possible, but the things that happen "as if by magic" are really the result of hard work and dedication to doing your best.
If you want to produce a DVD on your own, you can. But only after acquiring a lot of knowedge and skill. So start by shooting some videos, and editing them. And make sure you seek the opinions of people that aren't afraid to tell you when your video looks terrible. If someone tells you your sucky video looks great, they may think they're helping you, but their really only slowing down your progress. When you think that you have some good videos under your belt, get them into other peoples hands - post them here and elsewhere. Learn everything you can from the comments (especially the negative ones).
In the meantime, read books on success, video production, marketing, sociology, psychology, starting a business, budgeting, and of course magic and performing. When you see someone that is successful in an area that you're interested in, ask them what books they've read to help them achieve their success (you sort of did that with Wayne already. Good job!).
There is a lot to learn, but remember that you are only 13 right now. You have plenty of time to become excellent in anything you choose to do. If you strive for and achieve excellence, you will be rewarded with success.
As far as lucky breaks are concerned, luck is generally the byproduct of hard work. Just as 'magical wonders' that appear effortless are illusions that conceal the true efforts of the magician, 'lucky breaks' are illusions that conceal the true efforts of the lucky individual.
Here are some quotes regarding luck:
I'm a great believer in luck and I find the harder I work, the more I have of it.
--Thomas Jefferson
Shallow men believe in luck. Strong men believe in cause and effect.
--Ralph Waldo Emerson
