Thirty days at two hours, from knowing nothing. Every day is open right now — including the last one. Take them in any order, skip any of them, and come back whenever there is a minute.
Day 30 is not a deadline. A day here means the next day you sit down, never a date on a calendar, so nothing falls behind and nothing is owed. The ear course runs alongside from day one and finishes inside the month — 20 sessions, then done.
