I finally understand it. Its all about adaptability. The body and the subconsciouses mind is in a continuous adaptation to the environment it lives in. That explains why we always strive for new, better and cooler things, why we never are satisfied with what we have.

Be happy in the current position you are in, be grateful for simply living. It sounds like I'm on drugs or something, but we take such things for granted, appreciate and embrace what you have.
