For my first attempt at making the layout of the page I chose to divide the text into two columns per page and justify it. I decided to leave some space at the top as it reminded me of a little bit of a diary which is what is the text is supposed to be.
The font size for the main body and subheadings is 10pt, the heading - 48pt and leading is 11pt.
For my 2nd attempt, I chose to go for a more contemporary look which is not seen very often in books. I decided to not divide the text into many columns and chose to leave it as one justified text which is easily readable and pleasant for the eye.
The main text font size is 9pt, subheadings - 10pt, headings - 72pt, and leading is 11pt.
For my last attempt, I chose to go for a minimalistic look. The text is divided into 2 columns and it is left unjustified which gives it a little more of a chaotic look than the others but is still easy to read. I believe this attempt is the most successful out of all three.
The main text and subheadings font size is 10pt and leading is 11pt. The headings font size is set to 24pt.
