I've been reading motivational "how-to" books for decades and believe they do have some value, especially these 10 classics.

However, I have recently soured on them because they're mostly recycling the same messages and ideas

Motivational books based on interviews with successful people tell virtually the same stories with the same life lessons. 

Motivational books based on "science" are usually built around a single study that is not peer-reviewed and often custom-designed to match a foregone conclusion.

Motivational books based on personal anecdotes are usually puffy memoirs intended to promote a consultancy or a public-speaking career.

Motivational books that contain a fictional story are usually so trite or twee that they're almost impossible to read.

Finally, many motivational books become best-sellers--even New York Times best-sellers, because their authors paid proxies to pre-purchase thousands of copies.

That being said, newly-published motivational books must be of some value or they wouldn't get read and reviewed.

So, with that in mind, here are seven motivational books that were (apparently) widely purchased and read in 2017 and positively reviewed on Amazon.

Note: #7 is an outlier because it's quite original and also rather brave, considering that its subject matter is controversial... which almost never the case with this genre.

Option B

Subtitle: Facing Adversity, Building Resilience, and Finding Joy

Authors: Sheryl Sandberg and Adam Grant

Option B then goes beyond Sheryl's loss to explore how a broad range of people have overcome hardships including illness, job loss, sexual assault, natural disasters, and the violence of war. Their stories reveal the capacity of the human spirit to persevere and to rediscover joy."

Win Bigly

Subtitle: Persuasion in a World Where Facts Don't Matter

Author: Scott Adams

30 Second Summary: "Scott Adams was one of the earliest public figures to predict Trump's win, doing so a week after Nate Silver put Trump's odds at 2 percent in his FiveThirtyEight.com blog. The mainstream media regarded Trump as a novelty and a sideshow. But Adams recognized in Trump a level of persuasion you only see once in a generation. The point isn't whether Trump was right or wrong, good or bad. Win Bigly goes beyond politics to look at persuasion tools that can work in any setting--the same ones Adams saw in Steve Jobs when he invested in Apple decades ago."
