A great book to read that will boggle your mind with ugly facts is Affluenza by John De Graaf, David Wann and Thomas H. Naylor.
Read it if you get the chance - you wont be disappointed. It really made me take a good look at my life and the way I live.
Here is part of the blurb off the back
"Now revised and expanded, this bestselling classic shows how problems ranging from loneliness, longer working hours and family conflict to rising debt, environmental pollution, and rampant commercialism are all symptoms of the disease affluenza".
The most effective way to do it, is to do it.
