Hey alex great way to start steemit you are just becoming and adult and already earning income online and nice that you put 18 in your username years from now you will look back and always remember that is when you started.
I see you don’t have a Steemit Profile Picture I made a post to make it simple to do and win Steem/SBD. Here
Also here is a contest I have going on https://steemit.com/contest/@isteemithard/earn-high-curation-rewards-on-steemit-minnow-help-contest-everyone-wins
