When you become fascinated about an idea, the willingness to understand more, explore the topic, and ask questions is not 'a burden.' When people visit a museum, they are literally paying to learn, and they do not need to be encouraged to pay attention, listen, and read the summaries next to the exhibits. They learn because it is fun, and they love it.
This mindset should embody all learning! At preschool, elementary, and even secondary levels. What would the nation look like if all educators inspired scholars and students to Love Learning??
