I still have a lot to learn about Twitter, but there is one thing I now pretty much know for sure:
Who you follow on Twitter is WAY more important than who follows you.
Please don't get me wrong, followers really matter. No Twitter user wants to exclusively talk to themselves with every tweet. As I use Twitter more and more I have quickly realized that who I follow truly defines my experience on Twitter.
So instead of trying to get as many followers as you can, follow Twitter users that help you be more passionate and knowledgeable about what you do. Then when you decide to tweet/retweet your content will be that much more amazing. Then the people who see your tweets will have no choice but to favorite and retweet your tweets. And THAT'S when the followers come.
