someone else's heart pumping someone else's blood

This song has been stuck in my head non-stop for the past few days. I actually looked up the lyrics today and realized how amazing and inspiring they are! A good mantra for life. So I'm going to post the second verse for your viewing pleasure-- it's the one that hit me so hard.

"On the Radio" -Regina Spektor
This is how it works
You're young until you're not
You love until you don't
You try until you can't
You laugh until you cry
You cry until you laugh
And everyone must breathe
Until their dying breath

No, this is how it works
You peer inside yourself
You take the things you like
And try to love the things you took
And then you take that love you made
And stick it into some
Someone else's heart
Pumping someone else's blood

And walking arm in arm
You hope it don't get harmed
But even if it does
You'll just do it all again
