It is okay to not know the answer.
It is okay to ask questions.
It is okay to answer with, “I don’t know”.
It is okay to be wrong.
This is a sign of a strong individual. Anyone that can admit to being wrong, admit to not knowing the answer, or saying that they do not have the answer is the kind of person I like to communicate with. These types of individuals are the ones that will research the answer, help you find the correct answer, and will not guess the answer.
