Richard Branson said this quote

I don’t believe it can be taught as if it were a recipe. There aren’t ingredients and techniques that will guarantee success. Parameters exist that, if followed, will ensure a business can continue, but you cannot clearly define our business success and then bottle it as you would a perfume. It’s not that simple: to be successful, you have to be out there, you have to hit the ground running; and, if you have a good team round you and more than your fair share of luck, you might make something happen. But you certainly can’t guarantee it just by following someone else’s formula. Business is a fluid, changing substance.
