Samenvatting

Happiness and (mis)fortune are very individual matters of different origins: mental and material. They can not be (directly) traced back to each other. Prosperity can always turn into adversity and vice versa. This does not alter the fact that someone who has made courage or cheerfulness her second nature, has a different attitude to life than someone who, for example, has made lability into second nature. So if we can not opt for fame and fortune, we can choose to develop our second nature, and it is precisely those choices (plural) that make us who we are!
