If you appreciate history and are in the mood to get a deeper philosophical understanding of psychology or marketing (crowd mentality) then I would recommend "The Crowd: A Study of the Popular Mind" by Gustave Le Bon. It was originally written in French but a good English translation is available from Amazon for a very good price. It is short and written during 1894-1895 in France. I had to read it for my Masters in International Relations because of it's political history but it is also quite applicable for students of psychology, business or marketing as well. "The masses have never thirsted after truth. Whoever can supply them with illusions is easily their master; whoever attempts to destroy their illusions is always their victim." -Gustave Le Bon -Eric

I read some crime usually. it's not changed who else live. How have books changed your live?

One book that i love (only by seeing the cover page it started to like me XD) is The perks of being a wallflower because I was suffering about different stuffs and that book relaxes me.
