He's also one of my favorite humans on the planet.
He's shown up for me time and again (most recently at the Summit of Greatness last week).
He's the youngest person to travel to every country in the world.
He hosts one of the coolest annual events, World Domination Summit.
And he just wrote a new book on the easiest ways to make money . . . on the side.
Chris Guillebeau is a master of the side hustle.
