I really like that this book is broken down into bite-sized pieces. It makes making an improvement plan seem a lot more manageable. I think the premise of the book- that your success depends on your daily agenda- is very true. I also liked that the book has a workbook where you can apply the principles that Maxwell talks about.
However, a found the book to be a bit repetitive. I felt like it was more "90 days of advice on how to start getting serious about your priorities" than an "90-day improvement plan". But I guess, if the sole goal is after 90 days that you are more focused then it is an improvement. I guess from all the "hype" about Maxwell being a #1 author I expected a little more. All in all, it's not a bad book, but I wouldn't buy it for a friend.
