That is indeed how most people operate. Unfortunately I seem to have missed the bus. Even as a child I hardly asked for anything, and birthday and Christmas presents had to be practically forced on me. The same lack of ambition and desire has characterised my adult life. It's nothing to do with being able to work hard, I hasten to add, especially in music; that is quite different. Neither am I apathetic if a task needs doing.
In fact, with specific regard to music, I seem to create a lot more than most of the restless brigade do anyway. The acts of creation and playing are themselves the ends as well as the means. I know precisely the mechanism of the psyche Imbetter is describing because my wife and friends mostly think like that and such sentiment appears to memetically underpin the society in which I live.
I think it is possibly genetic, as my father and grandfather were both very laid-back - very active though, both mentally and physically, as I am, but lacking in the desire/gratification cycle so intrinsic to the modern world. A curious by-product is that I can remember only with effort what it feels like to be bored.
