Hola Nora,
Welcome to Steemit! You will love it all. This is a unique place where there is no competition. Instead, we all work together to help each other. The best way to grow is to have enough Steem Power and vote to reward other authors.
It is important to produce good content in a continuous way so you can grow.
A suggestion would be take your time to look for posts that interest you and promote them. Also, start by following the authors who publish good content and vote for them.
I wish you much success if you need help, let me know!
