Today we opened at random the Book of Joy: Lasting Happiness in a Changing World by His Holiness the Dalai Lama and Archbishop Desmond Tutu. We found this:

Every day is a new opportunity to begin again.  Every day is your birthday.

…

For a nontheist like myself, but who is a Buddhist, as soon as I wake up, I remember Buddha’s teaching: the importance of kindness and compassion, wishing something good for others, or at least to reduce their suffering. Them I remember that everything is interrelated, the teaching of interdependence. So then I set my intention for the day: that this day should be meaningful. Meaningful means, if possible, serve and help others. If not possible, then at least not to harm others. That is a meaningful day. —The Dalai Lama
