There are major disadvantages of constantly going against the grain. It may just be a reluctance to accept the outcomes of decisions others have made if you don't feel personally involved in the decision or recognized/respected by those who made the decision.
Or maybe you just want to go explore where other have not or will not go. You can miss out on a lot by venturing off, working in the small startup opposed to the fortune 500 company.
But really, I love how when I am around people who don't read, I read more. When I am around other people read, a read a little less, because I just end up talking to the people. Interesting books probably make interesting people-- So if you like being the contrarian and want to read more-- surround yourself with people who hardly read, lonely- but interesting--
