Stumbled across this in Dan Pink’s book, Drive:
You need not see what someone is doing
to know if it is his vocation,you have only to watch his eyes:
a cook mixing a sauce, a surgeonmaking a primary incision,
a clerk completing a bill of lading,wear the same rapt expression,
forgetting themselves in a function.How beautiful it is,
that eye-on-the-object look.
