There's an amazing line in Marcus Aurelius: "The healthy eye ought to see all visible things and not to say, I wish for green things; for this is the condition of a diseased eye." Maybe green is your favorite color - but if you saw everything as green, that wouldn't be a blessing, it would be an eye disease. By the same token, if there was no heartbreak, and everything happened exactly as you want - it would be a less beautiful and meaningful story than the actual story, where you're a part of a huge complicated mysterious whole.
