I took up running in college to clear up my mind between class and late-night studio work. Today I still find myself needing a good run to work through ideas, alleviate stress and recenter. I have space to think about the what, why, and how of my actions. My mind and body have become accustomed to some form of physical movement to feel balanced.
In the spirit of finding balance and purpose through physical activity, this video from Nike says it all.
Now go out and find your greatness.
