Maybe there's much more to learning to write than ten hints, but I think that if you did the following you could be sure that you were producing the best work you were capable of. Begin in the middle of things and catch us up as you go. Don't write the boring or mundane details of life unless you have a dramatic reason to do so. Make the reader feel what the character feels. Don't dwell on the scenery or setting, except as it dramatically motivates or illuminates the characters.
Actions have consequences, or ought to.
Every action in your story should lead on to a later action. Give characters a strong drive to accomplish something or to avoid something. Write regularly, and give your writing time priority. Don't be afraid to edit even your prettiest and most compelling writing if it doesn't fit the story.
