Unless I can read them like a book or they personally ask me for help, I won't do anything. Some people just let the world around them think whatever it wants to think and they just keep their life, their goals and their progress to themselves. Now I'm not saying that this must be the case for your friends or that they definitely on't need your help. But they definitely don't need advice from online strangers like us as the only image of them we know is the one you painted.
