Frustration.

It's where out hearts constrict, to the point where sometimes it'd be better if it were to explode.

When we know we can do better, but didn't give it our all. Just to have temporary relief.

It's a factor that both motivates and discourgaes us. Be it work and life.

Nevertheless, it's the same as being inserted into a meat grinder that we made with our own hands.

However, it also works backwards.
