Sunder there are many answers in the article along with that i totally agree with Alok when he says a real time exposure to the market is required. One may have had theoritical knowledge but the ones who have solutions beyond books only survive in todays highly competetive environment. One not only needs zeal and enthusiasm to be successful but also a business mind to succeed in new business. It requires ability to find solutions, ability to develop teams and ability to motivate and guide teams to achieve the organisational objective.
