I don't know what I don't know

I can't recall when I learned how to dive in Always forgetting to bring my oxygen I feel my heart turning numb The cold is leaving my fingers And now it's shaking my lungs I swore that I'd never get lost again Convinced that I found better ways Here I am searching for me again And it feels like I found something And it feels like I won nothing I don't know what it means to give up I don't know what it looks like to let go I don't know what I don't know I say that it all comes easily I say I was built for this I think it's time for a new design I sense old cycles repeating I'm tired of the whiplash And I know some things to be true You my dear have the power to change you And it feels like I found something And it feels like I won nothing I don't know what it means to give up I don't know what it looks like to let go I don't know what I don't know
