Whether you are writing fiction or a true story, without conflict there is no story.
There are three types of conflict:
1. Person vs. Person
2. Person vs. Self
3. Person vs. Environment or God
A short personal experience story will only have one conflict, whereas a book will build conflict upon conflict. However, one conflict may have more than one of the three components. When you are writing a short story, limit your characters to two to four. In a devotional or short anecdote, I’d limit them to one or two. Also, only have one conflict in all short pieces. In a book, you can keep introducing complication upon complication, solving some as you go along. But remember if you solve everything before the book is finished, your readers will put it down. Why should they continue reading? Build suspense; don’t tell it all. Surprise the readers. Don’t allow them to figure out the ending before you get there. Provide an interesting twist.
