"Whenever I find myself growing grim about the mouth," says Ishmael in Herman Melville's novel Moby Dick, "whenever it is damp, drizzly November in my soul; whenever I find myself involuntarily pausing before coffin warehouses . . . it [is] high time to get to the sea as soon as I can."
Use this passage as an inspirational kick-in-the-ass, Sagittarius. There's no need for you to sink into the emotional abyss Ishmael describes. Fix yourself before you're broken! Get to the sea immediately, and prevent the grey glumness from taking over. If there's no ocean nearby, then try the next best things: Walk along a river or lake. Immerse yourself for long stretches in baths and saunas and heated pools. Cry and sweat and come abundantly. Listen to music that makes you feel like you're floating.
