I ponder of something great
My lungs will fill and then deflate
They fill with fire
Exhale desire
I know it's dire

I think Tyler is saying that even though he's filled with a passion and desire to do something (I ponder of something great / they fill with fire) yet he cannot do the things he dreams of doing (and then deflate/exhale desire) and he recognizes the fact that he can't achieve the standards and goals he sets for himself.
