A life long love of learning is one of the most important things to develop in school. Knowledge is valuable in its own right and leads to a great happiness all on its own. Pure learning for its own sake is always the goal and it leads to a great happiness few people know about. Having the right motives towards learning and education is first if you want to find happiness in your studies and achieve great success in school.
All knowledge is valuable and you need to put your best foot forward and learn every subject that you study. Learn with pure learning being your goal knowing that the application of knowledge to solving problems is secondary though the schools put a lot of emphasis on using knowledge to solving problems. When high motives such as pure learning guide you, you will learn more of what you study and be better able to apply what you learn towards solving real world problems. You will also find a great happiness when learning that eludes so many students.
The goal of all education is to create a well-rounded student who will over time become a leader in his field and his community. This is why students need to do well in their classes. One day in the near future, each student will be making decisions as his field as an innovator that will affect the lives of hundreds if not thousands of people.
