I agree with Alex -- Who read newspaper and watch TV news regularly are prone to depression. As most people seldom read books which can make us think more positively in many things happenned in daily life. Books by Oslo, Buddism books, motivation book, Holy Bible...etc are good books to read as they can guide us to face things happened in daily life. (My English is not good, sorry).Thus, PR these type of books and activate them can make you have a significant life. (I am a Christian)
God bless you.
