There's a song Paul Dano's character's singing in "Swiss Army Man" movie.
Crazy, I'm freaking crazy, Maybe, just maybe I'll make it alone. Rescued, Thought I was rescued, But you're just a dead dude and I'm gonna die. There's gotta be a better way to get out of here
I can't understand what does "make it" mean in this context. General definition of "make it" is "to achieve one's goals". I can't understand what goal does the guy have.
