Dear all, I wonder where the notion comes from that individuals stop striving to improve (whatever), when they are satisfied. Or other way round: where comes the idea from that some degree of dissatisfaction is a good or even necessary impetus for activity or effort. On which theory is this view of man and human activity based? I am looking forward to your suggestions on where I could find the theoretical background of the idea of an inverse relation between happiness and effort.
Many thanks in advance. Susanne
