My dream job that will never happen is astronaut, definitely. Being recognized as one of the most all-around talented people in the country and being sent to space would be great.
I agree with this guy, being sent into space is what I'd mostly be in it for though.
Other than that, I would love love love to be a musician who makes the music he loves and has moderate popularity/success, more than enough to just live off the music. Of course I wouldn't realistically mind not being popular IRL but a man can dream.
