Not really sure what I'd say. If I warn them about things to happen, then they'll never happen, which would void me being at this point in my life and being able to warn myself. Telling them everything will work out fine sounds all right on paper, but it glosses over the parts where things won't be fine when they get to them. And telling them that it's going to be a crap shoot sometimes...well, that's not to good for the ego, either.

So...actually...probably nothing.
