A deed happens in a definite place at a definite time, but if it be sufficiently great and pregnant, its virtue radiates everywhere in time and space.
To paraphrase the philosopher Nietzsche, he who has a strong enough why can bear almost any how. I've found that 20 percent of any change is knowing how; but 80 percent is knowing why. If we gather a set of strong enough reasons to change, we can change in a minute something we've failed to change for years.
