The following quote is from 'The Pocket Thich Nhat Hanh' (click)
published by 'Shambhala Pocket Series'.
"In Buddhism, we have the practice of apranihita, aimlessness.
If you put an aim in front of you, you'll be running all your life,
and happiness will never be possible.
Happiness is possible only when you stop running and cherish the present moment
and who you are.
You don't need to be someone else; you're already a wonder of life."
