So I ended up picking a Statistics class rather than a math class, which... hell. I've taken both the math and the statistics so it's not as if the material is new, it's just that it's been several years since I took either class and this time I really, really shouldn't flunk.
For the past several weeks I've been receiving messages from the universe that have been telling me now is the magical time to take this class. The registration process was absurdly simple, I've had no trouble with parking or purchasing of necessary materials, the professor is my age and is something of an Asian nerd-hippie. Everyone I tell about the class is very encouraging. Yesterday, on my first day of class, it was even spelled out for me. Signs posted around the campus read: "We're proud of you."
Thank you, campus. Thank you very much.
