I came across an interesting blog posting by Carmine Coyote, during which she lists 4 reasons why adults should be more child-like:
Reason # 1
Children are encouraged to use their imaginations freely.
Reason # 2
Children are expected to learn; adults, heaven help them, are expected to know.
Reason # 3
Creativity comes naturally to nearly all children. Adults find it much tougher.
Reason # 4
Children are readily forgiven for making mistakes, where adults have sour notes inserted in their personal files.
Commenting on the posting, Bob Leckridge reflected further on the topic and included, in his posting, the book "Le Petit Prince". On www.antoinedesaintexupery.com, I found this quote from the book:
"Toutes les grandes personnes ont d'abord été des enfants, mais peu d'entre elles s'en souviennent."
