I took such things for granted. I have since come to realize that the more we have, the less we tend to appreciate it. When we get bored and unhappy we seek more and better things to help us recapture our excitement and joy. This applies not only to possessions, but to food, drugs, relationships, and any experience that we seek out to feel better. To the extent that we continue to look outside of ourselves for enjoyment and happiness, we run the risk of spiraling down into gluttony and depression.
Happiness is an internal state of mind.
It is foolish to continue looking for it in the external world. Only when you look within yourself can you learn to be happy. Unhappy people likewise find ample reason to continue to be unhappy. Ultimately, happiness is a choice from one moment to the next. The essence of willpower is the ability to choose one's internal reaction to the external world.
