Keep exploring.
If you remember the most joyful moments in your life, most likely you can tap into what brought you joy. Start getting serious about logging your happiest and saddest moments. Fill those memories with details--either real or imagined.
Try adding other poignant memories to your list.
Track these memories by writing them down--one per index card or one entry on your digital device or notebook. Keep them separated for now. You are beginning the log of your life's many journeys. It may become an autobiography; or you may choose one aspect of your life or a time in your life. Any one or all of these subjects will evolve into stories.
Hesitant about writing about yourself? Don't worry! Intrapersonal intelligence (knowledge of one's true self) is on of the greatest gifts you can share with others. If you want to avoid hurting others, you can always change the names and circumstances of your stories and memories. This is about exploring your own life. What causes distress? What brings joy? The more you understand the answers to those two questions, the more you will follow the path toward a content life.
Explore your life. Write down the stories of your life. Right your life.
