Is MBA needed to start a business........

Now a days many people have the feeling that an MBA is necessary for doing business. This may be one of the reason that organisations are looking for MBAs from well reputed institution for top post. This is forcing many young aspirant to do MBA to join the corporate world. When we see MBA gives the knowledge about business but also it reduces the risk taking ability of the individual. I have read somewhere Dhirubhai Ambani had said that if he would have done MBA he would have done all the work five years earlier. But i donot think so. An MBA has less risk taking capacity then an entrepreneur without an MBA. Dhirubhai may have failed miserably after doing MBA. Again in business you can not be always successful. The MBA peson will always look for the opportunity cost. If he feels that he has better opportunity in serving an organisation then he will join the organisation. But the entrepreneur will work consistenetly without any distraction. Here comes the difference. If you are successful when others are equally successful then you are not doing a great job. But if you are only few among the successful person that makes a difference. That difference is your entrepreneurial ability. Here the work of the entrepreneur reflects form the result.These are my personal view. I dont have any concrete example to prove my words but if i get any i will post that in this blog.
