The Academy Is... - The Phrase That Pays Lyrics Meaning

Hold your head high heavy heart.
So take a chance and make it big,
Cause it's the last you'll ever get.
If we don't take it, when will we make it?
I make plans to break plans,
And I've been planning something big, planning something big, planning.

OK, this is definitely about not waisting your life with bullshit, life is too short. Obviously ok.
