How likely is it to own a fast food franchise?

I was thinking that owning a fast food franchise would be a good career. How much does it cost to start a fast food chain and how likely is it that i will succeed in this career?

Do you have any restaurant managerial experience?

Do you have $600,000 to buy the franchise license and build a restaurant?

If you answered yes to both of the above then there is a 50-50 chance you would succeed.
