I’d say Satellite by Rise Against

You can’t fill your cup until you empty all it has You can’t understand what lays ahead If you don’t understand the past You’ll never learn to fly now 'Til you’re standing at the cliff And you can’t truly love until you’ve given up on it

It has an sort of “revolutionary politics” vibe as well in some other verses. That’s kind of Rise Against’s whole MO though, but I particularly like the lyrics from this one
