I have found that by being honest with my audience, I can be honest with myself and also forgive myself for imperfections- or more accurately, celebrate my imperfections.
Here’s a good template for your exercise:
On postcard write a secret [or many] about yourself. Something so secretive, you’d feel really uncomfortable sharing it with the world. Write it out. You don’t need to show it to anyone. It’s your choice. Be brave.
Glue the written side down in your journal. The secret is there- but it’s simmering underneath.
Then on the message side, write a message to the world.
