Welcome to Steemit, Tristan! I'm jealous that you're getting into Steemit when you're so young. I would have killed to have something like this available when I was 16.

Set your expectations for slow growth, enjoy the earnings even if they don't make you an instant millionaire, and keep practicing your blogging. Write about what you like, and the upvotes will (hopefully) follow.

If you need help, don't hesitate to ask the community. :)
