Kindness
“Oh man, you shouldn’t have”.
Kindness is a high leverage act.
Even mere considerations often result in an effect far greater than the effort put in.
And when we consider the asymmetry in perceived value vs. effort it is almost absurd not to choose kindness when we can.
Sure, acts of kindness do go unnoticed and we may feel short changed too.
But someone who habitually practices kindness never goes unnoticed for long.
