"Only one who devotes himself to a cause with his whole strength and soul can be a true master. For this reason mastery demands all of a person"

Albert Einstein's quote speaks to the idea that true mastery of a subject or cause requires an individual to commit themselves to it entirely. This suggests that a person should offer their full attention and energy to the cause in order to end up being a master. It is insufficient to merely have understanding or ability in a certain area; one need to also be willing to put in the effort and commitment to end up being a true master. This quote stresses the value of effort and dedication in order to attain success. It also recommends that mastery is not something that can be accomplished overnight, but rather needs a long-lasting commitment and devotion to the cause. In order to become a master, one need to be willing to put in the time and effort to truly comprehend and master the topic.
