Nothing? I know enough smart people in the social media and communications spaces to know that there are many people not singled out as “micro-celebrities” in their field who are quite capable of being superstars. Heck, they are superstars through what they do. When I tell people to blog or produce other content despite the intimidation of competing with a known “expert” in their industry, I simply say “Chris Brogan is not smarter than you (or insert name of favorite expert that works for you).” If you have any ideas at all, you are capable of sharing them in some form- teach, blog, speak, podcast, comment, rant at a Speaker’s Corner. It doesn’t matter, express an opinion, relate an experience, share what you are learning. Snap! You are a guru (I know, we are supposed to hate that term, but I actually hate all of them, so no matter).
Everything? The one big difference is just doing it. This is where you need to eat a can of ego spinach and just bull your way up to the podium. The best know the difference between adding value and just hearing the sound of their own voice- but at some point you need to be comfortable with the sound of your own voice.
You don’t have to be the best or the most popular. But you do have to do it. I learned very early on, when I chose to be a radio major in college, that you have to put yourself out there. Humility is great, shyness holds you back.
Go ahead. Say something.
