A popular YouTube video is titled "Every Principle has a Promise." It makes the point that living certain principles leads one's life to a better place. This also works in reverse; following a faulty principle can lead one's life to a lesser place, like eating the wrong foods can lead to poorer health. Principles come in many categories.

Principles—laws—govern all aspectsof life as well as the cosmos from the biological, to the physical, to the metaphysical.
