Here's how I would do it.
I know you want to start your own studio - so do I - but wait a few years to get the necessary experience. You may want to get a job in your field, and work a few years until you know the tools of your trade. After that, move to a smaller company so you can learn how a business is run. By this time, you may feel the need for more education, and, if so, get an MBA and/or upgrading courses. After that - you guessed it - work a few more years to put your new knowledge to work.
Then, when you have the knowledge and experience, as well as (hopefully) some money saved up, you can make the leap.
In general, it takes about 2-5 years to learn a profession and 5-10 years to learn how to run a business.This may seem slow, but, if you do the math, and you take the MAXIMUM time I have suggested, you will only be forty when you start your business. But you probably won't have to wait that long anyway - many people start their businesses in their 30's and do quite well at it.
I'm a middle-aged lawyer, and, as everyone here knows, I've been waffling for several years, but the time is coming for me to start filming. I've waited this long because I already have a different career, and so I'm working at that while I pursue my dream. You're luckier, because you are in your dream career, so you can start earlier. But, as I said, get the necessary knowledge and experience before you start.
Good luck!
