You can have everything and still be miserable. Or you can have relatively little and feel very rich.
Happiness is a state of mind.
Develop tools for how to get it. A young man once came to meet me in Jerusalem. He had an unusually happy disposition, so I asked him what's his secret. I was riding my bicycle when a strong gust of wind blew me onto the ground into the path of an oncoming truck. The truck ran over me and cut off my leg.
