If you don't do any of these then you are guaranteed to fail. These things give you a better chance of success.

Nothing is guaranteed here it's that kind of planet/universe. Maybe when you are designing the next planet or universe have no laws of probability always have guarantees, but then you will miss out on all the chance encounters and surprises.
