My goal is to survive reasonably intact and I believe that this is a biological imperative. Most animals have it.
I make do with what I have and I believe that an attitude of gratitude pretty much makes one happy with whatever one has.
I don't believe it's possible to have everything and I think an awful lot of people are very unhappy with what they've got because it's never occurred to them that they already have an awful lot to be thankful for.
That's why when people face death they come back changed. It's because in that moment they realized what was important.
What's important is simply being grateful for what one already has and valuing all the people around one. Think how terrible it would be to be alone on earth with no one to speak to.
