If you want your kids to have the best chance at success and intelligence, don’t spend money to invest in their education … that is a waste of money. The best shot you have is to surround them with a culture that highly values success and intelligence.
If you want your kid to read, read around them and surround yourself with friends and other associates that also read. If you want them to be active, be active yourself and surround them with activities and people who are active. The same idea applies to just about anything.
Kids won’t want to learn information that seems irrelevant to the world they live in. They will only want to learn information that seems interesting and useful. No amount of money, fancy educational materials or tutors will change this fact.
The largest reason that kids from wealthier families have a higher degree of success is not because of the money. It is because they are surrounded by a community of people who value the qualities that lead to success. Trying to throw money at people who are surrounded in a poor culture will only be a waste of money.
