Personally I only follow people who post content that Im interested in. When I started on Steemit I undervalued the power of commenting, but as soon as I followed some advices, just like yours, with the right way to "succeed" in the platform, my follower base started growing consistently.
I just found this video through a re-steem from one person that I follow, and that's why I follow the right people, I know every post and re-steem they make, it will be appealing to me, and its worth my time to check out the post.
