You will be wounded many times in your life. You'll make mistakes. Some people will call them failures but I have learned that failure is really God's way of saying, "Excuse me, you're moving in the wrong direction." It's just an experience, just an experience.
This is the real secret of life -- to be completely engaged with what you are doing in the here and now. And instead of calling it work, realize it is play.
(That last infirmity of noble mind) To scorn delights, and live laborious days; But the fair guerdon when we hope to find, And think to burst out into sudden blaze, Comes the blind Fury with th' abhorred shears And slits the thin-spun life.
