Martin Seligman : (2)

" There are physical characteristics which are inherited. These include things like good looks, high intelligence, physical coordination. These attributes contribute to success in life, and success in life is a determinant of optimism. " - Martin Seligman

" Life satisfaction essentially measures cheerful moods, so it is not entitled to a central place in any theory that aims to be more than a happiology. " - Martin Seligman
