It's nothing to do with intelligence. Many are just good marketeers. Of course, out of those who can market themselves, there are some who are truly good but it cannot be generalized into something to mean that all people who are successful are hardworking and smart. Nope, this is the case.

Actually, to me, i think a good leader is very good at identifying a good worker, if you perform very well, you will be recognised if you have a good leader.

If you think you perform well, still not recognised, then there is probably some issues which you don't even know or its time to change your job.
