I've recently been re-listening to Linkin Parks' Meteora album, so that's what probably got me to think of making a Zuko card in the first place. (Zuko... Oh, why did this series have to end?! WHYYYYYYYYYYYYYYY?!! )
(Fangirling aside...) The words themselves are for anyone who seeks for a way to move on from whatever obstacle life throws at them. (Please don't translate that as "Feel free to copy off of me." I really won't like that...)
Hope y'all enjoy!
