You have drawn The Study Girl. Whispering in a scribe's ear is a relaxing songbird whose nostalgic downtempo melodies grant focus and calm during an intense study session. Laid out before her workstation is many tools and scrolls, denoting a busy mind. This card is often associated with late night work grinds and intense sessions of knowledge crunching. If you draw this card, ask yourself these things. Do you need to chill and refocus? Are you enjoying what you are working on? Have you taken a break recently?
