James Mollison's photography project 'Where Children Sleep' illustrates this in its documentation the different lives of children around the world through their bedrooms or lack thereof. You can see the book online (here).
This book, perhaps more so than the tragic images of Australia, New Zealand and Japan, left me feeling that I need to be more grateful for what I have, to give more generously (not just when tragedy makes me feel guilty), to celebrate the little things, to be happy, and to live a beautiful life.

Wishing you all a rich, rewarding and beautiful day!
