George Matthew Adams

Character is greater than talent, genius, fame, money, friends - there is nothing to compare with it. A man may have all these and yet remain comparatively useless - be unhappy - and die a bankrupt in soul.

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.
