There's never going to be a decathlon that you're going to have 10 events that your satisfied with. You're always, always going to be dissatisfied in something, and that always draws you back to try to retry that the next time you do a decathlon. It's like you go for the perfect 10.
My parents gave me a strict upbringing, which at times has caused me to suffer distress but today I am grateful to them for it.
