This is a book which was written by positive psychologist and pioneer in the field of optimism; Martin Seligman. It is based on the notion that optimism can be understood as an explanatory style or attribution theory of how people make sense of their lived experiences, whether positive or negative. This explanatory style often to affects how people think about events in the future. Optimists tend to believe that things will go their way, whereas pessimists often expect the worse. In this book, Seligman guides the reader through the principles of learned hopeless (a trait commonly seen in clinically depressed people); as well as learned optimism and provides practical advice as to how to foster optimism. 
 

This is a free self-help tool aimed at increasing levels of optimism. It provides a light touch introduction to the concept of learned optimism and a worksheet of Seligman's ABCDE Disputation technique based on the principles of learned optimism. It can be thought of as a two part framework, used to identify and alter pessimistic thought patterns. The first part allows the participant to address the adversity, the underlying beliefs and the consequences of those beliefs in a given situation which gives rise to pessimism. The second part revolves around disputing these often negative, underlying beliefs by introducing contradictory and challenging evidence to foster a more optimistic explanatory style. The user is subsequently asked to take notes of any changes in energy levels as a result of havng disputed their negative beliefs.
