I read a book of his and felt that I was wasting my time, he was constantly rambling about nothing in particular, his points aren't clear and concise in my opinion. The theme of his book seemed to be, "You don't need an education, get out of the stable Government type job and run your own business, its the only way to succeed." Sure, running a business has its perks everybody knows that its easier said than done, Kiyosaki wasn't as rich as he lead everybody to believe until he wrote these books.
I've read a few personal productivity books and I think you can save yourself a lot of time by catching the simple theme of each book. For example Wealthy Barber is about power of compounding interest and starting early. Millionaire Next Door is about living below your means etc.
