We regret foregone opportunities more often than unfulfilled obligations. Yet we also know that a wholly realised life involves a mix of both dreams and duties.*
Daniel Pink

When he came to his senses, he said, ‘How many of my father’s hired servants have food to spare, and here I am starving to death!  I will set out and go back to my father and say to him: Father, I have sinned against heaven and against you.**
The prodigal son

Regret was a gift to one son but
not the other:
One chases home,
Regretting the choices he’d made, the other,
Still at home, hadn’t made the most of
what he had all along, and
because there’s no regret,
It remains lost to him.

**Luke 15:17-18
