If I want to act differently, I let go of the past.
If I want to act the same way I always did, I cling to the past.
Both clinging and letting go have their place.
I could cling to a habit of eating healthily, or treating others with kindness.
But maybe I could let go of a habit of self-criticism.
What benefits me? What benefits others?
What harms me? What harms others?
Who do I want to be?
