One day at a time
"I'm still alive. When I eat, I eat with all my heart; When I walk, I just walk; If I had to fight, this would be as good a day as any for me to die. Because I don't live in the past, nor in the future. All I have is the present. I'm only interested in the present."
If you can always hold on to the present, you can become a happy person. You'll find life in the desert, stars in the night sky, soldiers fighting because it's part of human life. Life is a festival, a grand feast, because it is always, and only now we experience this moment.
