Insights:

1. Eudaimonia is achieved by having virtuous behaviour - doing the right things for the right reasons.
2. Aristotle identified "akrasia" or "weakness of the will" as the major obstacle to increasing eudaimonia.
3. Eudaimonia is not happiness in the sense of a positive emotion, but it is a moral concept relating to values. Seeking a life of pleasure (wealth, power, sex) is not eudaimonic, regardless of how that person feels.
4. Eudaimonia is about self growth and affecting the world in a positive way.

References:

1. According to Aristotle and virtue ethics, humans should direct themselves towards virtuous behaviour as the purpose of life is to live in a eudaimonic way.
