Human creatures were always searching for happy and rewarding life from the very first day of the Earth’s creation. During the long centuries, philosophers tried to find the answer to this question, elaborating numerous methods and algorithms. A book Thanks!: How Practicing Gratitude Can Make You Happier by Robert Emmons is a contemporary attempt at this problem resolving. The latest book written by a professor at the University of California reveals the phenomenon of human gratitude as a key factor for life happiness achievement. The results of Emmons’s investigations concerning the various advantages of gratitude are discussed in the work. Gratitude is believed to have a very long history among philosophers and theologians of all times. And only at the beginning of the XXIst century did psychology finally select a deserved empirical place for gratitude having defined its importance in science.

The understanding of the fact that we are dependent on each other as well as the other things and processes in the world around us allows us to reconsider our previous worldviews and create a new technique of behavior and thinking. I found the confirmations in a book to the theory that only a person is a creator of one’s own life. Book material provided real facts of how gratitude can lessen depression, or how can it be a weapon against such negative feelings as envy, avidity, offence, and anger. A very illuminating section covers factors that undermine this virtue, including forgetfulness, comparison thinking, the negativity bias, perceptions of victimhood, and emotional conflicts.
