This is amazing. I've done 3 30 day challenges with my music. The amount of growth I experienced in that time was amazing. I'm currently doing a 14 day challenge. I run it the same way that i do the 30 day challenge, but I intensify the challenge. This is less of a develop-a-new-habit challenge and more of a productivity challenge. I'm all for 30 day challenges and I'm keen on trying out more. Thanks for the feature in your article.
