hevy, I liked it, I was going to post something abuot happiness, but no problem you came first,

Psychologists believe personality can, to some extent, be reflected by 5 traits: agreeableness, openness, conscientiousness, extraversion, and neuroticism. These ‘Big-Five’ are dimensions, not types, so all 5 appear in everyone to some extent. And they don’t sum up a person - they’re simply helpful descriptive tools.

Of special relevance to happiness are neuroticism, a tendency to be anxious, moody and easily upset, and extraversion, an inclination toward sociability, optimism and activity. Quite a lot of research suggests there’s a personality-happiness link: that happiness relates positively to extraversion and negatively to neuroticism. (1; 2; 3).
This link - and the finding that personality doesn’t change much over your life - has led some psychologists in the past to say happiness is genetically set (4). But these days psychologists see heredity as indirect - you can thwart unwanted aspects of personality by deliberate action (5) - such as avoiding triggering situations or consciously choosing to do things that may not come naturally.
Recent research supports the idea of a more indirect happiness-personality link:
Personality is only one influence on happiness (4). Other factors play a part - and may even counteract personality effects - in a person’s happiness level.
The happiness-personality link fades when you include happiness-generating behaviors (6). (There’ll be much more on these in upcoming strategies). That is, happiness has a lot to do with a person’s actions.
For instance, extraverts feel happier because they make more effort to manage their moods (7).
