We agree that learning is important. It needs many aspects of life. The problem is that a person’s ability to absorb and possess new knowledge is actually limited. Especially, in the age, which the information overloads like now, the amount of knowledge that can be learned already exceeds human capacity to absorb it. This means that with limited time, energy, memory, and other abilities, we need to give priority to learning strategies that can give us maximum results in limited time.
