"Any man who reads too much and uses his own brain too little falls into lazy habits of thinking"

Albert Einstein's quote is a caution versus relying too heavily on the composed word and not using one's own brain to think critically. He is recommending that if an individual reads excessive and does not use their own brain to think, they will end up being lazy in their thinking. This suggests that they will not be able to think for themselves and will count on the ideas of others. They will not be able to come up with their own concepts or solutions to problems. Instead, they will be content to accept the ideas of others without questioning them. Einstein is motivating individuals to utilize their own brains to think and create their own concepts. He is suggesting that if individuals utilize their own brains to believe, they will have the ability to develop creative solutions to issues and be more effective in life.
