Saint Ignatius

It is certain that, because the negligent do not struggle against self, they never achieve peace of soul or do so tardily, and never possess any virtue in its fullness, while the energetic and industrious make notable advances on both fronts.

The range of what we think and do is limited by what we fail to notice. And because we fail to notice that we fail to notice, there is little we can do to change; until we notice how failing to notice shapes our thoughts and deeds.
