To be fair, I haven't read this from end to end yet, I've jumped around and skimmed and read various chapters, but the book does specifically tell you to do that, so here is my review so far (subject to change as more is read).
Good things:
The first few chapters do a really good job of explaining what ADHD is and the problems associated with it without making the whole book about it like other ADHD resources tend to do. It would be good to show someone if you ever need to explain your brain to someone with incomplete knowledge about the disorder. It also puts an emphasis on the problem of knowing you have to do something, but not being able to make yourself, which is one of the hardest things to address and to explain to others. The chapters I've read and skimmed do have some good suggestions. The suggestions themselves aren't particularly novel (make to-do list), but they do have tips for going about those things to make them easier. The layout of the book with the short, titled sections and summary boxes is very ADHD friendly. I can see this book working really well for some people.
Bad things:
I really appreciate what this book is trying to do, and there are some suggestions in here that I want to try to implement, but for all its emphasis on the problem of knowing you have to do something but not being able to make yourself do it, I'm not sure the solutions are workable for someone who struggles with this aspect the most. To be honest, this might not be a fault with the book because I'm not sure there is a solution to that problem when it's sufficiently severe. "Stick to the plan," "do a little bit every day," "do x things at the same time every day" are all great advice for creating good habits, but if I could do those things I wouldn't need the book. There's some good stuff about how to get started on making yourself do things, but at some point, even the advice that seems workable becomes overwhelming in the face of all the areas of life it needs to be applied to. That's probably my overall reaction to this book so far: overwhelmed.
So, the authors tell you first to start off with a daily to-do list and a planner, and to utilize them every day. The daily to-do list is for things outside your regular routine that need to be done, and the planner is for the scheduling of your routine activities (school, work, things that already have a built-in timetable attached to them) and the things on your to-do list (chores, appointments, whatever). They advise you to keep the to-do list down to five items or less to prevent you from becoming overwhelmed (makes sense to me), and to schedule time for those tasks in your planner. The problem is that if you already have pretty much no successful set routine outside of school/work, or you're just a reasonably busy person, I don't see how it's possible to only have five items on your to-do list. Can anyone really say they only have five things to get done on any given day? Not to mention, the things the book urges you to prioritize in order to be successful take up three of your five slots to begin with (bedtime routine/sleep schedule, exercise, healthy eating), so now you only have two slots, so do I pick study one subject and shower (yes, I'm someone who actually has to think of showering as a task on par with studying or taking out the trash, so that really only leaves me one slot per day/per every other day) and be unprepared for class tomorrow? Or pick two subjects to study and just use dry shampoo in the morning? Laundry or dishes are definitely out of the question for basically ever because with only two spaces on my list, those will almost never be a priority until I have nothing to eat off of and nothing to wear. But then it gets harder, because you're encouraged to break tasks that require multiple steps into a series of smaller tasks, so really you either end up with many more things on the to-do list than recommended and it becomes, you guessed it, overwhelming, or your only task for the day is getting ready for bed broken down into five steps which just isn't realistic.
In order to help combat the problems people have getting started on tasks, the book does have some really good suggestions similar to or sometimes the same as the mindfulness techniques described in Lidia Zylowska's Mindfulness Prescription for Adult ADHD (I've had it for years and only ever managed to work through part of it). Anyway, it's a lot to do with recognizing negative thoughts/emotions and other barriers to the task, accepting them, and strategies for talking yourself into doing the task anyway despite discomfort. All of those things are actually really effective, but they're also mentally taxing, so I've only found them to be effective in concentrated bursts in situations that weren't overpoweringly stressful. Applying those strategies to self-motivate for each task throughout the day though sounds like a recipe for constant mental exhaustion and failure. That's basically feeling and working to overcome discomfort all day every day, and there's a list of mental steps you have to go through before you even get to physically doing what you set out to do. I don't see how it's possible to do that constantly and maintain momentum.
I also sometimes find the tone of the book to be excessively negative. People with ADHD already tend to struggle with a shitty self-image, and some resources combat that by reminding the reader that there are also some positive aspects to having your brain work this way if they're appropriately channeled. This book takes the few positive things associated with ADHD, calls them a myth, and explains how they're actually negative attributes. I mostly took issue with their characterization of hyperfocus as a myth, and was really just a response to pressure from excessive procrastination. It can be that, it can also be a problem with task switching, but sometimes I just get really into something and can't drop it. I admit that it can often cause problems; however, I'm sometimes able to get wrapped up in something I love and do it for hours and hours and hours, and in the right situation when I have the time that's actually pretty cool. They also took issue with people being "night people," implying that it doesn't exist despite research to the contrary that shows that different people have naturally varying internal clocks, and some people's are set later than others. In any event, insisting that people force themselves into an earlier sleep schedule they aren't comfortable with (and suggesting they might get cancer if they don't) if it's not necessary for school or work seems like a pointless hill to die on to me. Most of us have bigger fish to fry, and in the grand scheme of carcinogens most people are exposed to throughout their lives, I'm willing to bet the risk posed by being a night owl is minimal. There was also a lot of emphasis on negative statistics. I was helpfully reminded that people with ADHD are statistically less successful in life, worse drivers than drunk drivers when unmedicated, more likely to have relationship issues, and more likely to lead lifestyles that put us at risk for heart disease, cancer, and STI's. I'm not saying these aren't facts, or even that they shouldn't be stated, but I feel there should be some kind of balance in tone. I'm not sure it's beneficial for a self-help book marketed to a group of people with a tendency for really low self-esteem to put quite so much emphasis on how crappy our lives are likely to be, and how even the things that are sometimes perceived as positive attributes of the condition are actually just more things that are wrong with us.
Finally, I thought their chapter on emotions was somewhat lacking despite having some good introductory info, and their attitude toward marijuana is overly negative and outdated considering that in some states it's an accepted treatment for medication side-effects, and has also been successfully used by some to treat aspects of the disorder.
Despite my issues with the book, I really can see this being an excellent tool for some people, but those whose ADHD is more severe might find themselves with some of the same problems with it I had. I'm still going to keep working through it and trying to implement what I can, and I think it has some valuable insights. Even if I only get a few things out of it, any help is better than none.
