The only sufficient ingredient for success is luck. Luck is out of your control so the best you can do is to put yourself in a position that increases your chances of being lucky. That includes surrounding yourself with good people but fundamentally, the best way to be lucky is to keep going and not giving up. Perhaps that doesn't feel quite right because it's not sufficient, you're not guaranteed luck by being determined, but the alternative of saying "be lucky" isn't very meaningful.
