Three panel comic in the art studio. Pinch walks by Rookie who is painting a bowl of fruit.
Panel 1: Pinch says "Rookie! Looks like you've been practicing!" Rookie says "Thanks! I'm 'putting in the hours'"
Panel 2: An egg timer goes off. Rookie says "I heard it takes 10,000 hours to become an expert at something. 87 Down! Only 9,913 to go! I can't wait!!!"
Panel 3: Pinch says "That's not meant to be taken so literally." Rookie says "I heard I won't realize that until at least hour 100."

10,000 Hours

Who's been letting Rookie read Malcolm Gladwell?
