"Mr. Adams eventually included the advice—a list of nine rules that he dubbed "Everything You Need to Know about Personal Investing"—in his 2002 book "Dilbert and the Way of the Weasel." The list starts off with, "Make a will," and includes advice to fully fund a 401(k) and an individual retirement account and to invest retirement savings 70% in a stock index fund"
I would add my personal opinion that the broadest based stock index fund with the lowest cost is likely the best. Stay far away from anyone claiming to have a "system" for picking winner. A great deal of evidence indicates no one can consistently beat the market indexes by trying to pick individual winners. They won't give your money back after they prove they can't, either.
Sadly thinking about the Apple stock I sold for $29 a share many years ago.
