I agree with that, but it's not complete. Sometimes we view an event as failure but that's becasue we EXPECTED something else. For example we may expect to find our purpose and found failure instead.

That is the stress we need to avoid. Instead we need to rethink the event, perhaps it was a detour on the way to our real purpose, or pehaps in the event another was meant to see their purpose and thus we succeeded in our own, but may never know it.

"...failure is an event, not a person." but how we view any event as JB will contest too, is how we will manifest in our future.
