“How minding your Own Business” in Kiyosaki’s Rich Dad Poor Dad makes perfect sense

Source: Rich Dad Poor Dad, Robert Kiyosaki

I’ve been reading Kiyosaki’s book for some time now but I have always wondered about the concept of minding my own business. Not simply being nosy and all but rather just being preoccupied with the ongoing of other people’s lives through social media. How would I be able to build a business if I was preoccupied with the ongoings of other people?
