The concept of "50 rules of self-defense" does not seem to refer to a specific, well-known list of self-defense techniques or principles. Instead, the search results indicate that there are various books and resources that discuss life rules or principles, such as "50 Rules of Life" and "50 Very Short Rules for a Good Life From the Stoics." These resources provide general advice on how to live a better life, which may include elements of self-defense in a broader sense, such as emotional self-defense or mental resilience.

For those interested in practical self-defense, it's important to look into specific martial arts, combat sports, or self-defense courses that teach physical techniques and strategies. The "50 rules" concept appears more related to personal development and philosophy rather than physical self-defense. If you are looking for actual self-defense techniques, consider taking classes in martial arts, boxing, or other forms of combat training that can provide you with the skills necessary for personal protection.
