Early self-help classics such as Dale Carnegie's “How to Win Friends and Influence People” (first published in 1936) tended to have a specific focus on success in one particular goal. Although this trend continues, with common specializations in weight loss, health, or spirituality, a few contributors are becoming more interdisciplinary in their scope. As the field matured, authors began to integrate ideas gleaned from their peers, and a more comprehensive approach to personal effectiveness began to emerge.
