Who doesn't want to be happy? The obvious answer is: everybody wants. Every year on 31st December, when the clock strikes 00:00 Hours in the middle of the night, we start wishing 'Happy New Year' to our nears and dears, if they are awake at that time. On your birthday, wedding anniversary, festivals, etc. many of your friends and family members send you 'Happy Messages' and you reciprocate the same. The common word in all the above sentences is 'Happy'. In a nutshell, everybody wants not only himself/herself to be happy, he/she also wants others also to be happy. The International Day of Happiness is observed every year on 20 March. This most sought-after concept (of happiness) and techniques to achieve this state will be discussed in detail in this book.
