Well, my dad owns a semi-successful Promotional Products company and now because of his vision, that business is being passed down to me in a few years, and that business has been feeding the family since I was 11. The business, called Perfect Imprints, it projected to earn over a million in sales by the end of this year.
So in other words: Do what you like and if you work hard, maybe you can be successful. Sorry to not be super cheery and YOU CAN DO IT but I'm just saying how it is in the real world. But the best of luck to you.
