As an aspiring writer, you should just keep writing! The more you hone your craft, the better you'll become at it. I firmly believe that nothing worthwhile comes easy, and this also applies to writing.
You should never worry about whether your writing is "good enough". If you write from the heart and allow the thoughts and emotions that are inside you to come out, like magic, your writing will come across as being genuine, not contrived or based upon a template or formula.
