Joy has to do with seeing how big, how completely unobstructed, and how precious things are. Resenting what happens to you and complaining about your life are like refusing to smell the wild roses when you go for a morning walk, or like being so blind you don’t see a huge black raven when it lands in the tree you’re sitting under. We can get so caught up in our own personal pain or worries that we don’t notice that the wind has come up or that somebody has put flowers on the dining room table or that when we walked out in the morning, the flags weren’t up, and that when we came back, they were flying. Resentment, bitterness, and holding a grudge prevent us from seeing and hearing and tasting and delighting.
