I tend to read a negative card in advice position as the best possible manifestation of the card in question. So in the case of, say, Seven of Sword, you may actually need to be a bit sly and careful, maybe even avoid full honesty about something. For a particularly bad card, like the 10 of Swords, I might interpret it as fully accepting that something has ended and dealing with the loss, while trusting a new day will rise… and so on. I say “best manifestation” not in a moralistic way, but in a “silver lining” sort of way. This card sucks, yeah, but if I could find something useful about it, what would it be? That tends to be my advice.
