Blind leading blind?

This afternoon I got a call from a young woman who is finding herself in the same position I was in a little over a year ago.  She's considering graduate school, studying in my area of research, and was looking for advice and help making contacts.  I tried to help, I can remember so many seemingly futile efforts at making first contact.  I still feel like I got here simply by luck and a series of chance happenings, so I don't feel completely qualified to offer advice.  I also feel a little guilty about having gotten this opportunity.  Let me explain, one of those chance happening was being introduced to my current advisor at a meeting just over a year ago.  The young woman who called me today was also attending the meeting and also introduced to my current advisor.  Somehow, almost magically,  a year later I ended up here - hence the guilt.  I don't know, I guess I just feel unqualified to advise someone on how to get your foot in the graduate school door.
