So much of what people are trying to do with their petty demands is to work themselves out of holes they have created for themselves by saying, "I will only be happy IF . . ." and "I will be unhappy UNLESS . . ." But you could never get above ground zero that way.
It is certainly possible that people have made themselves SO miserable with their self-hypnotic ideas that they are obliged to do whatever they have decided that they must do -- OR ELSE! But, once one demand is met, do you seriously think that another doubt will not arise, and that another such demand will not be made? Think again! That entire process of doubt-demand-satisfaction is an ENDLESS cycle. A person can always say, "In order to be happy I need this house. Then I need children to be happy. Then I need this particular dress to be happy. Then I need this car to be happy. Then, to be happy, I need you to say THIS. Then I need you to do THAT." That process goes on and on. Quite obviously, that process does NOT work.
