4th Principle of Happiness At Work:

• Happiness relies upon a good level of self-understanding.

The happiest people believe that they have choice and control over how they look at things and what they can choose to do to control or influence things.

They know themselves well enough to understand what they need to be happy, what their strengths are and how they can play to these as much as possible, and also what failings and weaknesses they have that require their work to improve and develop.

And people who are Happy At Work are able make close correlations between how they see themselves and how they are seen by people around them.
