“Every person takes the limits of their own field of vision for the limits of
the world.”
— Arthur Schopenhauer
Value, seek, and hear the opinions of others. Doing so always creates a better solution. Failing to do this leads to misunderstanding, division, and ineffectiveness.
Note, I did not say “accept or attack others’ opinions.” Other people’s opinions are valuable because they help you see beyond your own limitations. They need not be accepted, raw, as your truth. Nor would you be wise to defend aginst opinions that don’t seem to match your own.
