I like Dave's straightforward approach to... pretty much everything in life. Finances, business, employees, parenting... The list goes on and on. I was listening to his podcast almost daily for 2 years and I still enjoy listening to it occasionally. He really helped me to solidify certain rules for myself and, yes, also get out of debt. My finances were not horrible, but nothing to be proud of either and now I can see a drastic change which I attribute first and foremost to his principles.
Now, I may disagree with certain things - like putting his Religion as a cornerstone, but I can't (and shouldn't) judge. I may have some other principles, but it doesn't change the outcome. So, even if you're atheist or you hate George W Bush (apparently Dave loves him) or you don't think porn is a problem - just get over it, as long as you don't work with Dave his principles won't affect you, just benefit from the words of the guy, who in my opinion impersonates common sense.

TL;DR

Great book for any entrepreneur. Pure common sense instead of theories out of the thin air.
