It's hard to be an introvert in a world that places high value on extraversion, and looking through the lense of society, we feel "less than", and wrong somehow, and this is reinforced of course by those who are not like us, as it suits them to be "better than". I suppose what I'm saying is, don't buy into the myth that introvert=someone who is not good enough to be an extravert.
Whether you realise it or not, through introversion, you really add so much to the world. Put simply: in a world of blaring radios, it is you who can choose to change the channel.
