All people should be taught the financial advice that if you're going to invest your money in something where you don't need to do any work, put it in index funds that are diversified according to the timeframe of your investment. There is simply no other way to get a better return. Sure, if you have some specific talent or think you can multiply your investment with actual work (e.g. if you're a landlord but actually manage the property yourself), sure, go for it. But if you just want your money to make money without actually doing anything, putting your money into nearly anything else will have a worse risk/return balance.
