Well, I'm still quite new myself :p I see Your introduction post haven't had much of an impact, I'd suggest to go to the new or early (a few hours) trending posts and find some followers there.

Your posts/comments should be meaningful, related to the topic. You definitely shouldn't write short messages like 'good post' or ask for upvotes or followers, it might get You flagged. Self-upvoting yourself is a controversial move but most people don't perceive it as a bad behaviour for minnows (minnows = small players like You or me, single upvote doesn't yield more than ~0.40$). When posting something, You should go 50/50 since SBD (Steem Backed Dollar) is now more expensive than normal STEEM and it's easily exchangeable for aforementioned SBD. The rest You can find on FAQ alongside with the links provided there. If You have any specific questions, don't hesitate to ask :)
