Yeah, thousands of desires as such, when one is fulfilled, I look onto other, and then another and then another..
Maslow's need heirahy theory explains the same, when a rational man (I wonder why do they exclude women) fulfils his Phsyological needs, he looks on to Safety needs, then towards Social needs, further to Esteem needs and then towards his Asthetic needs, finally analyses himself whether he has attained Self Actualization.
