How do you define Hapiness?

For me happyness is when I can see the beauty around me. Happyness is to be and to feel close to the ones that I love, my children, my wife, my mom, my siblings, my friends. Happyness is to know what I am doing and where I am going. I do not need to feel in control but I need a certain understanding of where I am going. Being benificial to earth and society but also the scientist in me, understanding what everything is all about. how it works, what it really is.
