#1: Creating delicious entertainment for my friends.
#2: Creating and collaborating on story premises, characters, and encounters/situations.
#3: Watching light bulbs go off over players heads as they unravel mysteries.
#4: Having an outlet where the more I invest creative energy, the more I see the quality of my craftsmanship improve
#5: Always practicing improv and honing wits
