What is the best advice you can give to a writer that wants to write but never writes?

Just imagine it in your head and get a basic idea of what you want to write but sense you won't write the story, tell the story to supporting friends ask their opinions about it and if they like it keep doing this until you get a more completed story and feel encoraged to write it or maybe pay someone to write what you say but I do feel like I need to tell I'm not a professional or anything and this is just my honest opinion and of course if you don't have some one you feel comfortable telling the story too I recommend you keep telling the story too your self and if you want you can do what I do and put on some head phones listening l to music go to the back yard and walk around (maybe even dance or pretend to be a character fighting something/someone idk) and think about the story just my opinion of course.
