Great book for adding new beneficial habbits and remove the bad ones. Unlike most “positive” and “big change” self help books, this book suggests to change little things in daily life and get greater results on the long run. If you want instant change, don’t bother to read. But instant change self help books discuss imaginary success and not so beneficial, it is not my opinion, it is fact. You can research about it. This book includes the most beneficial tips of whole other books and thus is Greatest habbit book. I hope you got my point.
