To me the story of Aragorn has always been the story of the poor boy from humble origins and with humble mind forced to show his qualities, forced to learn his stature, forced to take his place that is so unlike his own view of himself had been.

It's like this Sartrean/Nietzschean "become what you are!" - or the traditional "growing up" -story.

So to me Aragorn has always looked a bit reluctant to seize the power the fate has given him - and he only slowly realises that that is the case. And why is that? Because he has been brought up in humility. Take the people of Bree who thought him just plain weird but he didn't make a case out of it; he just silently left the mock behind - to guard the lives of those who scorned him... Well, that's what I'd call humility...

Let's not forget that he had done that for ages before the things started to roll forwards and we only see the part where he struggles to find his new identity as the story-told king of all men.
