Secular Daily Devotional
"Each entry is drawn from a different field of knowledge: History, Literature, Visual Arts, Science, Music, Philosophy, and Religion. Read one passage a day and you will explore each subject once a week."
I love daily activities , but rarely keep up with them.
On Day One you learn that "Several letters in modern-day English are direct descendants of ancient Egyptian characters. For instance, the letter B derives from the Egyptian character for the word house."
I'm not certain of a daily activity, but I expect that many of the facts will trigger some rather interesting writing prompts.
