Well, first, you can start by brainstorming all the possible scenarios that can stem from the ideas for real life stories. Let's say you have an idea about a friendship. You can think of all the good times, the arguments, and the reconciliations that can happen in a friendship. Then, you need to find a unique angle. Maybe in this friendship, one friend has a secret that could change everything. Next, you should outline the story. Decide on the beginning, middle, and end. For the middle part, add some twists and turns. For instance, a new character could come in and create a rift between the friends. Finally, keep writing and refining the story as you go along.
One way is to focus on the characters. Take the ideas and build characters around them. For example, if the idea is about a small town's mystery, create characters like a curious journalist, a reclusive old man who might know the secret, and a young detective. Then, plot the story around how these characters interact with the mystery. Another way is to base the story on real emotions. If the idea has a theme of loss, explore how different people in real life deal with loss and translate that into the story's characters. Also, research is key. If the idea is set in a particular time or place, research that thoroughly to add authenticity to the story.
