You need to read something awesome! Read some articles and books written by experts in business. There are many different philosophies, many different approaches. Read about "creating blue oceans," for example. Google this: blue ocean strategy
You can also read Good to Great by Jim Collins.
I do not have any interest in getting an MBA but I read these because they are SO interesting!!
The books and articles are like the wood for the fire of your essay. No wood, no fire. :-)
