Any analysis you would recommend of JVtV? Does the volcano represent that Joe has to overcome the imagined fears that is preventing him from growing in life?
For starters, he quit his job before the volcano opportunity came up. He choice was never "keep working or jump into a volcano."
He quit his job because he'd just been told he had just a few months to live, and didn't want to spend them like that.
Finally, he didn't have much money. He could either scrape by in his apartment for a few months, or go on a grand adventure and die just a little earlier than he would have anyway.
