My experience is this: If we didn't have to sacrifice something in order to do something else, then our choices would carry very little meaning. We'd also be a lot less free than we may think we are, and we'd probably learn a lot less about who and what we are. Sounds like a photograph of a polar bear in a blizzard.
When I make the time to think about, which I usually don't, I'm grateful for many of the things I lost, gave away, or were taken away from me.
Not too long ago, I'd have wondered how I could believe something that sounds so crazy.
