I think the choice you made is the smart one. It's what you feel strongest about, so it will be easier to stick with. Also, you'll end up with a great health that you will only have to maintain, so the business thing will be easier, too.
Your post burst with confidence; the only thing missing was the background music.
It's clear now that you're on the right way - and you made your decision in time, too!
Congratulations!
