It isn't complicated, really. Stop thinking about it, I tell myself. Just do it, Nike says.
Chop wood, carry water. Be good. Be kind. Be fearless. Live so that you carry few regrets. Shower the people you love with love. Worry less about what others think of you, because for the most part, they don't. For me, Saroyan said it best:
In the time of your life, live—so that in that good time there shall be no ugliness or death for yourself or for any life your life touches. Seek goodness everywhere, and when it is found, bring it out of its hiding place and let it be free and unashamed.
Place in matter and in flesh the least of the values, for these are the things that hold death and must pass away. Discover in all things that which shines and is beyond corruption. Encourage virtue in whatever heart it may have been driven into secrecy and sorrow by the shame and terror of the world. Ignore the obvious, for it is unworthy of the clear eye and the kindly heart.
In the time of your life, live—so that in that wondrous time you shall not add to the misery and sorrow of the world, but shall smile to the infinite delight and mystery of it.
