Everything is relative
Your truth is a vantage point

Right and wrong, big and small, beautiful and ugly – everything depends on your human perspective. A house is enormous to an ant but tiny to a mountain.
What you consider 'the absolute truth' is usually just your own, very limited vantage point. Others stand on other hills and see other landscapes.
By acknowledging that all opinions are relative you become more flexible, more tolerant – and much harder to offend. You no longer need to defend your hill against everyone who sees something else.
Reflection
Pick an opinion you hold tightly. What does the question look like from the other side's vantage point?
Today's practice
In a conversation today: sincerely ask 'How do you see it?' – and listen without preparing your answer.
