Dragan, surely you're not interested in semantic contradictions. ;-) Human history does show that you have to strike while the iron is hot. "Expense" is an efficient description of the reason- not necessarily monetary, either. Whether we be politicians, managers or parents, many of our regrets are not about things we did but about things we didn't do when we had the chance.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
