Start T-ing more
If you like Twitter you have probably RT-ed something meaning "Re-Tweeted". This is a way of saying, I also think this is cool and I want my friends to see it too.
However, if you have too many RTs you gotta start T-ing. Said again.
If you've got more RTs that Ts you aren't being creative enough.
I am all for sharing other people's information and do it quite a bit, but I find it hard to believe that there are so many people that still don't think what they have to say is worth a blog post or worth a T.
It is! Your voice does matter. Maybe not to thousands of people yet, but you do have something unique or interesting to share. So exercise your creativity and start T-ing more than you RT.
Disclaimer - T something that adds value to you, your friends or the world at large.
Godspeed.
