Self motivation books (also called self help books) are now ubiquitous in any respectable bookstore, and they are in great demand, cornering various market segments (male, female, rich, middle income, low income) and age brackets.
Self motivation books have been around for decades, like the works of philosophers and sociologists which analyzed life's purpose and gave views on what an ideal life should be, which inspired mass movements and led to major historical developments in the world, like the abolition of slavery, the women's liberation, and the triumph of democracy, among other things.
Napoleon Hill, a newspaper reporter, was credited to have published the first official self motivation book in 1928, titled The Law of Success, a result of over 20 years of interviewing and writing the formula for success of the world's richest, most accomplished and most powerful figures of Hill's time, including inventors Thomas Edison and Alexander Graham Bell, billionaires John Rockefeller and F.W. Woolworth, statesmen Joseph Stalin and Theodore Roosevelt, and businessmen Henry Ford and Jennings Randolph, among others. Hill's work gave rise to the self motivation movement in America and became the model for many self motivation books and resources that came after it.
