Rewrite help!! Samuel Johnson's sentence in modern english retaining its meaning and basic structure.?

Good writing and good speech are two different things, and although someone who excels in one might be just as successful in the other if they had the opportunity to practice it, yet many people can speak well without preparation even if they know nothing about the more precise and demanding methods of writing. In the same way, it is also quite possible that people who are well educated in the study of writing may lack the quick thinking and understanding of colloquial language that are needed if you want to be an entertaining conversationalist.
