I had the honour to appear on Calvin's podcast and the level of compassion and insight in a human psyche was a big surprise. 
You're the one is a reminder of how we all carry with us insecurities, that often hold us back when we try to take the next step. And yes, often you go through the flow, your obligations but those mind bugs are still there. And Calvin succeeds incredibely in reminding you, that you have value. You are the one that brings what you bring to the table. 
Clear concepts, simple exercises but with a positive impact.
