Welcome to Steemit! Thanks for participating.
It’s true that you can make some cash here but I recommend that you temper your expectations. Steemit is really just a game and while posting quality content is certainly part of the game it’s not the end all be all. In order to be successful you’ll need to engage, be yourself and be persistent. Don’t get discouraged when your posts don’t make anything and have few views, it takes time for people to get to know you.
My advice would be to spend a good portion of your effort thoughtfully commenting on other posts as much as possible so people can get to know you. Stick with it, bring your true self and think long term and I have no doubt you’ll be rewarded in the end.
