This week Leveling Up Episode #11 with Joshua Smith www.GSDMode.com

Always be an extremely polite, open minded skeptic. Never lose your ability to question.... curiosity usually exists for a reason.

Heres an awesome quote from French Philosopher Denis Diderot,

"A thing is not proved just because no one has ever questioned it. What has never been gone into impartially has never been properly gone into. Hence skepticism is the first step toward truth. It must be applied generally, because it is the touchstone. "
