Hope and happiness
"Hope and happiness are obviously related. Hope will typically add to happiness and happiness will feed hope. Yet empirical research does not always find strong positive correlations and sometimes even negative links. To understand these differences we must first define the concepts and consider the measurement of these," says Prof. Ruut Veenhoven , one of the world's leading experts in happiness research. Hope is the expectation that things will turn out well in the future.
