If you're for the business, no need for an MBA IMHO. But if you want to excel with the rankings in the academe or corporate, it's a ladder.
When you have good capital to start a business, an MBA degree is not needed, but when your business has started running, you need people with an MBA degree to work with you to build your business.
you don’t have to get a mba to read and learn if you have the will and desire then you can learn pretty much anything
The learning comes from experience with what we do and that's the same with business. Some get lucky that they find their success through their first tries.
But if we're going to speak the entirety of the whole circle of business, failure is the first step into success and look at the every successful businessman, they'll say the same thing. Having an MBA is like a bonus.
Failing and losing in business is a very normal thing, but failing and then quitting is stupidity, business is not easy, there are even people who have started a business for years but haven't succeeded either. The point is to be patient and confident in the business you enjoy doing.
