There's the moment where he switches from autopilot to consciously taking advantage and appreciating each moment, from impatience with his situation to nonjudgmental presence. The result is a shift from self to service. He finally finds meaning in providing succor to those in need. Is there any other real meaning?
His service falls short because he isn't able, and so he has a reason to improve himself, and does it in earnest because there is now a reason for it. From the unexamined to the examined life.
It all happened after he had exhausted all other channels and he was ready to hear the words of some random person: "Maybe it's not a curse, Phil. It just depends on how you look at it." It wasn't just that, of course, but the entire life building up to it. In his case, he had to suffer a lot. Not a surprise, given his overbearing personality.
And in making himself a servant, he becomes the most interesting man in the world as a side effect. But the pleasure of being a virtuoso in his own life may not "matter" compared to his focus on service, but it's a natural and appropriate collateral benefit.
He disengaged his need to connect his intentions with the results. All he could do is what he could do and the consequences are what they are. In a Buddhist sense, he escaped the habit of desire.
And I like it so much because it's a resurrection story, and how doesn't like that? I like it because something like that happened to me once upon a time.
