Personally, I have a hard time pacing myself when reading a book. So, I make tasks (or subtasks if you're a Pro!) to create tasks for each reading session. Examples help:

I have "Go Dog Go" with 20 pages. I want to read it in 2 page increments, each session being about 5 minutes.
So, you create a task "Go Dog Go", and make (sub)tasks "1 - 2", "3 - 4", ..., "19 - 20", each with a 5-minute estimate attached to it.

Easy peasy! Need a deadline? Just slap a due date on your task (or subtasks). Whether it's for class or book club, due dates got your back!

You might think, "That's all fine and dandy, but I have a 200 page book. I don't want to sit around and make dozens of tasks..."

I made a MilkScript to help you create tasks/subtasks for each reading session.

It asks you for:
[required]
- Book Name
- Total # of Pages
- Target # of Pages To Read Per Session

[optional]
- Due Date
- Page You're On
- Reading Session Length (minutes)

As a bonus, I added a warning if you have too few days to read the book by the due date at your intended pace. Better pick up the pace!

Just another reason you should buy a Pro account!
