Get better at storytelling

Focus on the central point of the story.
All details must lead to this central point and be somewhat related. If you have to ask yourself why you are mentioning this person or detail, it only serves to dilute your story and message.

Choose an emotional payload for the central idea.
Human beings are emotional creatures.This means that if you're going to tell a story, you have to make sure that there is an emotional payload. When people get to the end of your story, they should be laughing, crying, feeling angry, or any other emotional reaction.

Paint a picture.
Try to include a lot of sound and dynamism in the details of the overall narrative.
