What appears bountiful today may disappear tomorrow. But hoarding serves no one – if a thing is valuable enough to be missed, it’s too valuable to let pass without enjoyment. The most valuable things are precious precisely because they cannot be preserved; you can’t save a beautiful day for a rainy one.
Sometimes you’re safe. You don’t need to guard against danger or scarcity. So let those feelings fade from your mind when you can, and let the others bloom.
