Well, its a bit complicated but, yes. (Exceptions are always there, obviously)
Its not that Introverts are less talented or Extroverts have some extra talents.
Its just that, in todays world, success depends on your talent, your passion and the network of people you build over the years.
Its not about what you can do, its about being considered to do that in the first place. E.g. Consider there is a position for which you are perfect. The final decision is to be taken between you and some other guy, and the other guy gets the job, just because he has a habit of throwing some “hi’s” here and there everyday. Doesn’t seem fair, does it. Well, that’s how it is.
But guess what, passionate people have always proved people like me wrong. So, best of luck.
