Happiness

Ive recently been reading a book about happiness. What is happiness, that is such a weird word and invention of our society. What is it really? And can we ever relish that slippery piece of puddy when we have it between our fingers. One of the ways to improve happiness the author suggests, writing down 3 characteristics of happy people. Once you write them down those are the things you need to fix in your life in order to be more happy in YOUR life. Its an individual thing and there is no wrong or right answer.Here are mine.
Happy People:
1. worry less
2. help others
3. are satisfied
4. feel like they make a difference
