Once you have completed your ideas wait 24 hours, then go back and read it again. You will find many things you could have said differently or other way to express the sentence. Also you will discover a great deal of grammar mistakes you never would have caught before. Read widely and voraciously. Read the classics, by learning how others have developed their skills it will better help you in the future.
Writing is a craft that requires both talent and acquired skills.
You learn by doing, by making mistakes and then seeing where you went wrong Write from the soul, not from some notion about what you think the reader wants. People will express what you write differently. Remember no two people are alike and no two opinions are alike. You can make someone happy with one paragraph and yet the same paragraph will infuriate others. Write to please yourself, your opinion is all that matters.
