I don't believe that people truly look for advices from another individual; I think they just seek reassurance -- I think this is what I want to do... but I would like to hear someone else agreeing with me. Is there those who truly have no idea what/how they want to do? In fact, I think by deciding who they go to for "advices" they have already made the decision what they want to do. After all, we will only go to those close to us for advices, wouldn't you already have an idea what friend A would tell you versus friend B?
Then, everybody should have 1 or 2 friends who will always tell you the truth, no matter how bad it sounds. But be ware, do NOT go to said friends unless you are ready to hear what they have to say. :)
