In Mihaly Csikszentmihalyi's book 'FINDING FLOW' he says that people are more likely to be happy if they are:
Healthy; Extrovert; having strong self-esteem; in a stable marriage and have religious faith.
Oh well, perhaps my strong Spiritual Faith will keep a smile on my face. And.....I can be quite extrovert after half a bottle of red wine = maybe I should drink more.
