Being a good CFA /CA /MBA is different from being a good and intelligent businessman .Ideally a person should be a good CFA/CA /MBAas well as a good businessman .While there is a method or path to become a CFA /CA/MBA there is no specific path to become a good business man .Some are great business thinkers by birth ( i.e family genes )  , some acquire through voracious reading , some through association with other businessman and some a combination of the above 3 .

But I would say that its is relatively easy to become a CFA/CA/MBA but very difficult to become a great business man ( i.e business thinker ) as in the former case there is at least  path how to become but in the latter case there is no specific path .

Yes, very true.
