Do you admit your ignorance on the subject..and tell them to find someone who is already successfully achieved the results they are seeking...or try to point them to someone you know who is there?
Or do you use them as test monkeys and point them in a direction you are thinking of trying but afraid to do so. Or act like you know the answer so they do find out your true ignorance on the question? Furthering everyones ignorance..and hindering progress towards a real answer for everyone?
Like a highway to your goal...along the way there are many back roads.(decisions) that could be shorter ways to the end of the highway or dead ends. say you take one..and realize you could be lost...do you ask a fellow hitchhiker for directions? or search for someone who is at the end of the highway you are traveling for advice?
Who is going to get you there as soon as possible and easier with less mistakes?
