"He preaches well that lives well"

This quote by Miguel de Cervantes is a tip that actions speak louder than words. It is stating that an individual's words are only as meaningful as their actions. If somebody is preaching about a certain lifestyle, however not living it themselves, then their words are not as effective or meaningful. This quote is a suggestion to practice what you preach and to lead by example. It is likewise a suggestion that people will evaluate you based on your actions, not just your words. If you wish to be taken seriously and have your words be meaningful, then you must measure up to them. This quote is a suggestion to be mindful of your words and actions, and to make every effort to live a life that follows what you preach.
