The evidence in favour of calmness is huge. Practices like meditation and mindfulness improve life expectancy, productivity at work, health and even personal happiness. And you can reach Calm any way you like: take a walk with nowhere to go, savour a chocolate on the tip of your tongue, plant a seed, doodle pointlessly, notice the world around you. Smile, breathe and go slowly.
