La gestion de projet pour les nuls is not what you called an easy book to read. I've learn a lot of information, maybe too much actually.
At some point I really taught that I was reading a book for my school. It was maybe too much to handle.
Doing some small resume everyday really helped to keep track of the book.
I learned more that I enjoyed but I can say that if you really suck at handling a project, at the end of the book you will feel special like at least you've learned something.
It's a big book, so if you're lazy I recommend you to separate the book in part so you won't feel like it never end.
I still feel like I've learned things that i will use, but you can't remember everything, I suggest to people to take this book as their bible for their project, that's what I will do.
A good point was the multiple examples in the book, cause whenever I felt like I was missing something they expose it with a real life example and situation that I could be a part of one day. It was a way for me to get out of the school zone that they settle.
To Conclude,
Good Book but way too big and to much information to handle
