You can already get the important part of your point across with the briefer title. There's no reason to have a subtitle. It doesn't really add anything and just makes it come across as bloated.

I like A because it is more positive and uplifting that B with "when the world refuses to cooperate.

Option A has a better tone and ring to it. It gets to the point and tells you right away what you are getting and what it has to offer. The rest of the language in the other options is superfluous and doesn't seem to add anything. It is also too long and would take away from the rest of the wording. It tells you what you want to know and makes the book seem like it has something new and different to offer. Option A would appeal to a wider audience of people and would make them more likely to check deeper into what the book has to offer.

Definitely Option A. The title is more straight and to the point which I really like.

Option A is able to describe what the book is about just as well as B without being overly wordy. A book title shouldn't be a book in and of itself, sometimes longer isn't better. If I still wasn't clear on the subject/context of the book, I can read the back cover summary or read online reviews.

i like a shorter more concise and to the point title

This one is short simple and to the point. The other one seems too long and like it's trying too hard

I chose this option because the title was shorter and more to the point. I feel that a longer title like the one in the other choice would turn people off from reading it.

simpler and more direct gains my attention better

Straightforward. No extra words needed. To the point. Readable at a glance.

I like that the idea is all on the individual instead of waiting for the "world" to cooperate, which sounds like an excuse.

I like this option better because its shorter and has powerful language. Both options sound great but A goes more to the point

The other title is too long and I would be worried about my time being wasted on wordiness.

I like how it's a shorter saying and don't have the ending that B has because that sounds confusing.

This option was more concise to me. B got really long and clunky and awkward.

This book tile is more concise, to the point and compelling.

I like that it’s more simple. It’s straight to the point which I like .

The title is a lot smaller than the other title which very long and complicated.

I think a more concise title is much better and more memorable.

I like option A because its short and simple, which is much easier to read on a title than something long like option B.

I prefer a simpler title. Option A sounds interesting

For book titles, I have always found that less is more. A super long title loses my interest pretty quick, so A would be more likely to get me to take a look.

I wouldn't purchase just from the title, but I would click on A over B.

I think the shorter, simpler title is more appealing.

I like option A. It sounds more positive, upbeat, and energetic. It also has a nicer sounding flow to it in my opinion. I don't care for option B, I think the title is too lengthy.

I like Option A because it was more concise. I feel the book would also be direct and concise.

I think the other is a long title that is not inspiring. Short and sweet is better.

I prefer Option A because it gets the point of the book across with a minimum of words, it is concise and strong.

I like the shorter title--it is easier to remember.

I like this is directly to the point and makes me want to read it. The longer the sentence is when im shopping, the less my eye will be attracted to it.

I prefer this title because it's short and to the point. The other one is long enough to be a blurb instead of a title.

The shorter title is better. I think when things are too long, I'm inclined not to read it all.

I prefer Option A as my first choice. It's a more affirmative message in general. There is no added sentence to hinder you but rather a clear and straightforward thought with a upbeat tone.l

Option B is too long and wordy. I don't think I'd even finish reading the title if I saw it at a bookstore. I like A. It's short, precise, and to the point.

I feel that the other title is a bit too long and it doesn't really make you want to read it. I feel that titles should be short and sweet.

The title of the book looks very much appealing to me and makes me to read the book. So that I selected the option.

I like the addition of "even when the world refuses to cooperate"

A makes it seem like it's a parenting book more than a success book. I think B does a better job stating what the book is about in the title.

i love how wit motivates me already

This is the book title I would be likely to click on and be likely to buy. This is the book title that stood out to me and grabbed my attention the most.

This provides a little more context to what the book will be about. A is more vague.

I think the expanded title gives a bit of additional info on the fact that the author knows that things don't always go easy and we always come up against obstacles.,

I like B because I like the last sentence. It gets my attention first and sounds more interesting.

Added impetus by the last sentence. I immediately felt compelled toward that more impactful addition.

This option seems more detailed with the sentence afterward

This makes it sound intelligent. You should always assume the world is out to get you.

Seems to have a more define detail of the title

I like that the title demonstrates the challenges a person faces to improve themselves.

I prefer option B "In Your Power: React Less, Regain Control, and Raise Others... Even When the World Refuses to Cooperate" book title because it is more pacific when it indicates the world and it's problems.

Option B has the feeling of a complete thought. This is a statement that is understandable as many consumers have been put in the situation feeling that the World refuses to cooperate. Option A has conviction feeling to it of power but might be a little overwhelming.
