I would say to create something in text, pictures, audio or video in as little as 15 minutes a day and sharing it with the world has the potential to change one's life over time.
This is because after 67 days it becomes a habit, a good addiction so to say, the one which we wait for during our day.
Then sad and painful experiences don't make much of an impact on us because our lifes become more centered and focused.
If you don't know what to create, simply document your day noticing something you did, something you saw or something you heard other people say.
Because of this habit to create a short funny comic strip about Pinky and Spiky every day and share it with the world, I was able to create this today:
Hope you will create something and share it with the world before you hit the bed tonight.
