Albert Einstein's quote "The only resource of expertise is experience" is a pointer that knowledge is not something that can be acquired with books or lectures alone. It is something that has to be gained via straight experience. This implies that expertise is not something that can be educated, yet rather something that should be learned through trial and error. It is through our very own experiences that we gain knowledge as well as understanding. We need to be willing to take dangers and also make errors in order to learn and also grow. By accepting our experiences, we can obtain a much deeper understanding of the world around us. Ultimately, it is through our own experiences that we get knowledge as well as knowledge.
"A lawyer without history or literature is a mechanic, a mere working mason; if he possesses some knowledge of these, he may venture to call himself an architect"
