I want to become an author and improve my writing, but I need some advice first.?

Hello dear, I have to same problem! Love to write but it never ends up feeling right for me. The advice I could give to you currently and what kinda helps me is to have a notebook dedicated to your story. Then take time to write out your characters, describe them in detail and also do the same with your main events in your story. :) Draw pictures in the notebook of things and people in your story:) Its not to much of helpful advise but this helps me often:)
