It seems to me, thinking about this self-discipline thing some more, that although I am inclined to aspire to a life of leisure, in fact, such a life would not be good for me. What would be good for me would probably be a life of some leisure, with other time devoted to some big projects of some sort.
Otherwise, where would self-esteem come from, if all I’m doing with my life is loafing about? I may aspire to leisure, but I would also like to do something: to be someone as it is commonly known. This is the desire for fame that many people seem to have: the desire not to be an unknown nobody, but to be someone who makes a difference.
So effort is built-in to the human psyche.
