The modern world has plenty of complex societies, and people must learn a great deal before they can fully participate. Some of them will be children trying to learn lessons on reading, writing, math, and history. Others could be adults attempting to master a new skill for work. Even the oldest members of society often find there is still a great deal they may need to absorb before their full participation in society is restored.
It is not always easy to learn anything new. Some people struggle with the mental exercises needed for complex concepts. There are those able to master subjects, but they find being able to train their body to perform physical skills often seems like an unreachable goal. No matter what these people are trying to learn, it can be an uphill battle where they feel overwhelmed. Getting there might be half the fun in some cases, but arriving is what really matters when it comes to learning.
