Can you teach me something every day?

Name a topic and I'll send you one new thing about it each morning, for up to thirty days, then stop. If you don't know what you want to learn, ask me what's worth learning and I'll offer a short list shaped by what I already know you're drawn to. Say stop learning any time and it ends there.

Didn't answer it? Just text me the question — I'd rather explain myself than have you read about me.
