The landscape of history is made, on the whole, not by great people doing great things, but by the accumulation of everyday actions by everyday people. That is the background on which the large-scale action takes place, and the context without which it makes no sense. It still contains great people doing great deeds, but there are far more ordinary people in the world than there will ever be heroes.

PPS - The exact same person in a lesser context, doing the same things, is less impressive.
