Lyric discussion by Paraless 

I think it's about someone who talks a lot of shit ("talk yourself up") but when they reach an obstacle that gets in their way, they can't figure out how to get around it ("you've hit your one wall, now find a way around"). Before this occurrence, Hayley had thought the world of this person but after, she realizes that they were all talk in the first place.

By the way, speakupxdear has got to be the luckiest person alive.
