In a season fourteen episode of The Simpsons (“I’m Spelling As Fast As I Can”), Lisa asks her mom Marge if the family can afford to send Lisa to college. “Not on your father’s salary,” Marge replies, “but I could...give piano lessons!” When Lisa protests that she doesn’t play piano, Marge shrugs. “I just gotta stay one lesson ahead of the kid.”
Whenever I’m trying to do something where I feel underprepared, underqualified, or underskilled, I just tell myself “stay one lesson ahead of the kid.” It’s silly, but it helps me focus in on small, actionable things I can do rather than becoming overwhelmed by the enormity of the task facing me.
