If you want to be the best in your field, here's a simple trick: create a new field and be the only one in it.
Take two or three or four things that you like, combine them and you're done.

Twitter = short attention spans + texting + blogging
YouTube = video + internet
iPad/Tablets = smartphones + laptops

You get the idea. Each of us is unique; no two people like all the same things. Your stand-alone position will always be available to you -- the question is if you'll take it.
