This quote suggests that it is unnecessary to remember information that can be easily retrieved from a book or any other source. The underlying principle is the efficient use of our mental resources. Instead of cluttering our minds with easily accessible information, we should focus on understanding concepts, developing critical thinking skills, and fostering creativity.

In the context of today’s world, the quote holds even more relevance. We live in the age of the internet where information on virtually any topic is just a click away. This abundance of information at our fingertips allows us to utilize our mental capacity for higher-order thinking skills such as problem-solving, decision-making, and innovative thinking, rather than for storing facts.

When it comes to personal development, this idea encourages us to be more strategic about our learning. Instead of trying to memorize everything, we can focus on understanding the fundamental principles and concepts, and then look up the details as needed. This approach not only makes learning more efficient but also more enjoyable. It allows us to be lifelong learners, constantly absorbing new knowledge without feeling overwhelmed by the need to remember everything.

Moreover, this quote also highlights the importance of adaptability and flexibility. In an ever-changing world, the ability to quickly access and utilize new information is more valuable than having a rigid set of memorized facts. By not committing everything to memory, we are more open to new ideas and perspectives, and better equipped to adapt to new situations.
