/ˈlīfˌhak/
a simple, clever tip or technique that makes it easier and more efficient to do a familiar task... such as when posed with a question & asking yourself "Does this job or project align with me?" or "Do I want to go out with ___ tonight?" then simply waiting for your body to physically react and give you a response.
Being vulnerable and learning to trust yourself through the cultivation of that innate discernment is what will align you with your higher self and better-evolved version, that is a promise.
