We each can and many often do. Evolution ‘wired’ our brains to help us thrive.
Generosity generates smiles of gratitude. Smiles from recipients trigger 'feel-good' hormones that add bits to a donor’s inner peace.
Those bits of peace merit a special name, perhaps a 'quantum' of peace.
More though: 'benefitting' leads to 'gratitude' and that adds a quantum to a recipient’s peace.
.
So goodwill and helpful action generates at least two extra quanta of peace.
Over time, peace grows from sensitive helpfulness in communities.
That's how easy it is to make peace stronger. And that way fewer problems will be left in need of later, scarce and more costly help.
