Will I be happy once I get that thing?

For example, I bought a new car and am now waiting for delivery. Naturally, I pay close attention to this matter, going onto the forum every evening to check and research related information. Why do I do this? It is just an ordinary car; it won’t bring any substantial change to my life. I know that as soon as the car is in hand, I won’t pay attention to it anymore. The key point of the problem lies in my obsession with the “desire” for external things. The fixation I have towards external things that bring me happiness and joy is actually a kind of delusion.
