Denial

Once one has almost everything life can bring (within reasonable boundaries, of course), there's no much excitement left. Ironically, the excitement might come through denial. You're not allowed to do this or that, you couldn't get on a plane, you couldn't get the girl you were longing for, etc.

It's pretty hard to catch the plane once it's lifted off so one can be angry (or just excited) but there's not much that can be done about it. On the other hand, being denied/refused/turned down by a chick brings more creative ideas how to get her, thus pushing excitement further. Until she gives in, or, alternatively, an average asshole grows bored/frustrated that his chances are slimmer than being ran over by an F1 car in Sahara desert. And gives in.

However whatever happens in the end is unimportant - the initial joy of denial for a numb been-everywhere-done-everything-seen-it-all bastard is rejuvenating.

Unless the denial comes too often, in which case the poor bastard should start pushing his boundaries further. Or just get used to whores instead.
