Personal development is a concept that has been around for centuries, with ancient wisdom and philosophical texts serving as some of the earliest written guides. However, it wasn’t until the early 20th century that the modern self-help movement began to take shape.

His principles, outlined in the bestselling book “How to Win Friends and Influence People,” emphasize the importance of building strong relationships, practicing good communication, and approaching challenges with a positive attitude.
