Welcome to Steemit!
I have no doubt that if you keep posting, you'll do just fine. Hell, I entered a competition to have access to your mom's advice! She really seems to know what she's doing. I remember how hard it was as a teenager to listen to advice from my own parents. But keep writing and you'll do fine, no doubt.
I have to say though, I think you missed an opportunity not picking @arbitrarykid as your name. It's still available...
