There is a tradition in internal arts that in 100 days of concentrated training, even seemingly unattainable things become possible.One hundred days. Just over three months, like a long summer vacation. What can we accomplish? It can be anything: art, a spritual practice, music, fitness, writing, thinking, anything. Choose your goal and share it with the rest. Give updates, inspiration, and support, and take the same from the journeys of others.
