I have tried to set the things that I care about in my life up such that failures are interesting. What I mean is the places that I focus most of my time (my company, writing software, surfing) are those in which failures (ideally) imply learning. Since I like learning things, this is enjoyable. Hence "persevering" (fixing my mistakes, learning not to make them again) is fun, and thereby easy. This hasn't always proved possible for me. You mention relationships: I haven't ever found a way to make failing in those fun.
