Unique and reliable "experts" appear before elementary school students who are struggling with issues such as "I'm not good at tidying up," "I keep putting off my homework because I'm so obsessed with games," and "My grades aren't improving as much as I'd like," and provide passionate instruction to teach them important things that they should learn but that they won't learn at school.
