I wouldn't say that this book is the holy book for procrastinator, but I'm gonna say that this book helps me a lot. The tips & tricks weren't so cool, but that's what I like. I don't really like those self-help books that are full of tips and tricks because somehow, they didn't actually solved the root of the problems. But, this book somehow solved my problem. Now I wouldn't want myself to be perfect anymore. I prefer to do things now rather than perfectly. Of course, this is not perfected either. I'm still procrastinating but to the lesser amount than before. Surprisingly, much lesser!
The writer is actually a psychologist, and experienced in the field of cognitive therapy including procrastination therapy so that wouldn't make this book a pseudoscience just like other majority of self-help books. So, this book is trustworthy enough. Besides, this book can helps you if you don't want to go to psychologist for the therapy session.
