In my experience, the Seven of Pentacles deserves a lot more credit than it tends to receive. Here are some of the meanings that this card holds for me, sorted into two categories; Shadow Work and Light Work.
Shadow work *can* refer to a card that is reversed (upside down) in a spread, but this isn't always the case. Consider its influence upon the other cards surrounding it, as well as the situation for which (or person for whom) the cards are being read.
Alternatively, Light Work, doesn't necessarily refer only to "right side up" card ~ it could be a hidden blessing, an unknown helpful force, or even the 'light at the end of the tunnel'. Above all, trust your intuition.
