Content with Life

I was going out for a car wash and suddenly it dawned on me that how many of us out there is actually content with their life? Or should say is there any out there who are content with their life at this point? Taking a car for example, when we were younger we hoped that we're older soon so that we can drive a car. When we're older then, we hoped that we got a job so that we can afford a car instead of driving that old wrecked. Then, when we finally got ourselves a job, we got ourselves a car. Yay! A car! How awesome is that right? Nostalgia might only last for a few months in this case cause sooner or later we will want something better than the one that we own now. But, the question here is - will this be taken as a sign of materialism as seen by others or as a challenge to improve oneself in life? Personally, I would say it's a little bit of both. Who wouldn't wan to look cool when driving around town? Honestly there's no point in denying it. So, who's content with their life???
