Step 1 Create Twitter account
Step 2 Start following people you think are interesting
Step 3 Tweet and retweet interesting stuff
Step 4 Follow everyone that interacts with you via replies, retweets and likes (see Bonus tip below)
Step 5 Repeat steps 3 and 4 hundreds, if not thousands of times a month.
The hard part is step three. It’s easy to retweet interesting tweets, but it’s another to craft interesting tweets yourself. It can take a long time for you to develop your voice on Twitter. And it can feel like it takes forever just to break 1,000 followers. But if you stick with it, and you’re mildly interesting, you’ll reach a tipping point around 2,000 followers where your follower count starts to just grow organically without performing step four. Even so, you should keep doing step four indefinitely, but perhaps be more selective in who you follow.
You’ll know that you’re doing it right when your tweets are getting retweeted and liked by others. But even when you get to be rich and famous, don’t stop following back, it’s arrogant.
Bonus tip: Don’t follow people who you don’t want in your Twitter network. For instance, I don’t follow racists, homophobes, bigots or people who are just assholes. Life is too short to have negative energy sucks in your life.
