It takes time to build your Steem Power. The best approach is to keep viewing other peoples posts, commenting and upvoting (even if no effect due to low steem power). Hopefully others will upvote your comment. It then takes 7 days before earnings show in your wallet. Comments should be of quality. It seems that the quality of the comment has an impact.
It will all take time but you will gradually build it up.
Also review the section on introductory posts to get an idea of doing one, and then do your own introduction post. You need others to get to know you.
When you do an introduction post let me know and I will resteem for you. The same for any other quality post you may do.
