How long does it take to write a book and how should I plan my series, details here?

So I'm writing a book with 365 arguments and I started last Wednesday and so far I have 238 arguments. Each of my arguments contain enough ideas for at least 10 pages of writing it not 60 pages so I am undecided between

a) Dividing my 365 arguments into 4-6 books and writing 10 pages on each argument.

Or

b) Creating multiple books for the exact same 365 arguments where I use different examples for each argument in each book. So 10 books and 10 examples for argument 1. 10 books and 10 examples for argument 2 etc...

Or

c) Turning the arguments into journaling or group discussion prompts and facilitating it as a host and student type of group activity.

Or

d) doing all 3 or a combination of 2 of these ideas.
