There are a lot of good "Top 5" type articles on tips for new steem users. I'd start out with those (I don't have any particular ones to recommend). Also, I'd recommend posting regularly and commenting (thoughtfully) regularly to build up a brand around your account. The following will come from you bringing value to the Steem ecosystem. This sort of behavior will raise your reputation score and rewards. The more rewards you have in Steem Power, the more you will earn from community upvoting of your content. Is that a helpful start?
