Don’t Half Ass Two Things
Ron is trying to convince Leslie to take a sabbatical and focus on her campaign and not split her time between campaigning and the Parks Department. He tells the story of himself in middle school trying to complete schoolwork while working at the tannery and a sheet-metal factory and how it wasn’t worth trying to “half ass two things.”
Ron’s advice is that even though Leslie can do both things, she should specialize in her campaign. Trying to do too many things would cause Leslie to experience diminishing returns rather quickly and she could achieve a lot more if she focuses on less.
