The nearest that I come to metaphysical thinking is this philosophical argument: If we were created by God, then we were given an infinite gift.
After all, from a human perspective, it is infinitely better to exist than not to exist. Everything that we cherish and value is predicated on our existence itself.
But that gift comes with a caveat. In this line of thinking, God gives us exactly one chance (as far as we know) to build a life filled with meaning and purpose. The rest is up to us.
In other words, nothing is actually handed to us other than the opportunity to make the most out of our life. Within that philosophical framework, phrases like “I deserve more” or “What that person has should be mine” are essentially meaningless.
Whatever you start with in life, you have already been given the astonishing opportunity to make the most of the infinite gift of life itself. And that’s a helluva lot, when you stop to think about it.
Of course you can always choose to decide that this is not a particularly good deal. But then you may already be on your way to squandering that gift.
