the hammer, or the nail?

I just finished watching a movie where "El Condor Pasa (If I Could)" played over and over.
Not the whole song - just the first verse.
I'd rather be a sparrow than a snail
Yes I would, if I could, I surely would
I'd rather be a hammer than a nail
Yes I would, if I only could, I surely would

I didn't really notice the song because it fit into the movie just fine.
Afterwards, however, the song popped into my head, and I immediately thought "I would rather be the nail."

Huh?

The movie was about a woman who was beaten down by life, and she struggles through her personal demons to eventually become a happy, well-adjusted human.
So, good for her. The hammer smacked the crap out of her, but she eventually became the hammer and is a strong woman.
Or, something like that.

And, I totally get that. I usually agree with it.

Today, though, I think that it's the nail that's the most important part of the equation.
Yes - it gets hit by the hammer, but they both suffer an impact. (The nail more so than the hammer due to its size, but...)
The nail, though, is only hit a few times, and then it's done. The hammer moves on to the next nail and more impact. Time and again. Overall impact to the hammer is more...

The nail, on the other hand, holds everything together for what seems like forever. As a mom - and a middle child - I think it's not a bad gig. Right?
