Thanks for putting this summary of Rich Dad Poor Dad & The Richest Man In Babylon together -- both really great books!
I think I agree for the most part.
For point 5, I'd say use credit cards to buy stuff if need be, just make sure you have to cash to pay back the card. If one says "never buy anything on credit" it would directly imply to never use a credit card, because credit cards are always based on credit.
Credit cards, when used, and paid in full so that it never accrues any interest is exceptionally good because:
1) It makes your credit score go to the moon, which means you'll save an enormous chunk of money when it comes time to get financing for a mortgage.
2) Credit card points = free vacations (i.e. one of your biggest regular expenses are reduced to 0. For example, I'm going to Italy soon for 2 weeks and I don't have to pay a single dime for nice hotels -- and these points are generated money I would have spent anyway, and I incurred $0.00 interest on it since I just pay my CC in full, every time).
