~ The belief that age is the only relevant measure for a person's worth (ie someone younger cannot be as worthy as a relatively older and more experienced person). I think this statement is good only in such articles atleast in India. I haven't seen this in action anywhere in India. India's corporate is hierarchical. The Indian culture also teaches the same right from the younger days. If there are 2 people who could qualify for an promotion and one is 28 yrs old and the other is 35 yrs old, always and always only the 35 yr old person will be person who bags the promotion.
Yes I do agree with the author. Jim collins gave a concept for successful companies, which can be applied to personal professional lives as well. Try to choose a career that should intrest you, one you are best at and the one which should drive your economic engine.
