There is much out there about time management & productivity, but I have read no book or seen no program that covers it all (from the basics, life's purpose, routines/habits, properly organizing your information, clearing your head, journaling, what effects the environment has on you, renewal, health, what effects the internal drives of the human biological machine has on productivity, inner friction, outer friction, etc...) There are a lot of gaps to be sealed and I think you could do that extremely well.
But I would even more interested in a book about polarity. Definitely. I don't understand it perfectly yet, and I would love to read an in depth book about it.
Good luck with making up your mind!
