Not my words - but I do like them (one of my business connections down here in Aotearoa dropped them on LinkedIN this morning.)

The first mile is owed, the second is bestowed. The first is mandatory, the second is voluntary.
The first mile belongs to others. The extra mile belongs to you and you alone.
It is therefore always in the second mile where character, nobility and greatness lie.

I tried to source them - but nothing specific came up, though a version of them seems to be part of ‘Chick-fil-A’s’ service program. And - no attribution - other names that emerged in the research included Ayn Rand and Jordan Peterson.

Alrighty Then.
