Prince Harry and Prince William suffered a devastating loss when their mother, Princess Diana, died in August 1997. Although William and Harry have reportedly become estranged in recent years, their late mom allegedly left them with some invaluable advice, and "important warnings," before her death.
Diana's former private secretary, Patrick Jephson, told People, "If they study Princess Diana's life carefully—and I hope they often do—William, Harry, and their advisors will know that she left them many good examples to follow and also a few important warnings to heed. Public affection and the rich rewards of royalty must be earned with self-sacrifice and service."
