Do you know what you want

You know the moment where you know what you want , and you really want to get what you really want ? Eventually , we will get what we want , but in our own different ways , as soon as the end of our fingertips touch that particular thing . There is no words to describe the happiness we feel , the joy and satisfaction . But after holding on to it for a while , we start questioning ourselves , is this what i really wanted ? and soon come to realization that the thing we wanted and had , did not serve the purpose we wanted it for .
