Hello Yessica and welcome to the Steemit Community! What I can tell you is that if you don't understand the overall mechanics of how it works there are a few basic and easy steps to be successful. Be patient and post good content. Upvote things that you truly believe are valuable to you. You can upvote about 20 times a day without effecting your voting power. It's honestly that easy. In time you will understand how it all really works but for now just enjoy the ride!
