Do you have a video where you explain the big picture of this "second brain"? Because I don't fully understand the connection between the elements. For example: I'm writing a book called "Math Problems for 1st Year Students". The book has 50 chapters that I need to divide into sections and plan what I need to do each day. Then I need to handle marketing for the book, automate emails, send it to the printer, and so on. How do I now enter all of this into the second brain so that the connection is clear and I know what I need to do each day? I apologize for my poor English.
