I often reflect on whether it is has been worthwhile studying for MBA. My opinion is a resounding no.
I spent three years studying for MBA whilst I was a middle manager in public sector desperate to get a director level post. The feedback I used to get from my failed interviews was that I did not have a wider exposure to business for a senior level post. There is so much more to business than accountancy.
I paid a heavy price for gaining a MBA. This was the amount of my out of work time taken up in reading, completing assignments and examinations. This time could have been far better used gaining life experience. When I was young I did not fully appreciate the importance of time.
I think experience in business is far more valuable than a post graduate qualification particularly if you have your own business. It was all very well learning about how other organisations have handled problems and how they could have been dealt with far more effectively. Hindsight is 20 20.
I do not think you really learn till you are faced with the situation and have to deal with it. Furthermore, each situation is unique you just cannot apply what you have learnt in a unique situation.
I did get my senior level post at a price that on reflection was just not worthwhile.
Reading widely on business and gaining life experience is far more valuable than an expensive MBA.
