I think it is crucial for kids to learn how to reflect on their lives as learners. In the beginning of the year, and throughout the year, we can teach students how to be reflective on their reading lives and practices.
On the first day of school, during Reading Workshop, you may choose to focus your mini lesson on creating an emotional Reading Timeline. While you model creating your own timeline, you are teaching students to think about their reading life and what has worked and not worked for them as readers. While students create their timeline, you can begin conferring with your kids, getting to know them as readers. During the share component of the Workshop, students may have time to talk with a partner about their timeline.
A next step (or you could start here), could be to have students elaborate on their reading life timeline with quick notes. For some, it is easier to "talk it out", so offering talk time before elaborating may be useful.
You can help your students "keep these notebook pages alive" by revisiting the timelines throughout the year and asking students where they fall "emotionally" on the timeline during the given point of the year and why.
I believe that the relationships we have with each student has great impacts on their motivation and achievement.
Most importantly, as teachers, we influence our students' reading life greatly. Strive to be part of the reason for the "smiley face" on a child's reading timeline.
