For my personal 26 Books in '26 challenge, I'm aiming for a non-school book every two weeks.
When I started reading In Praise of Slowness on the first as my first book of the challenge, I decided to aim for 1/10th of the book a day - it works nicely for that book because there's 10 chapters, but for other books, I'll just divide the page count.
My reasoning was that if I had a day where I didn't get my reading in, I'd still be okay. I can even miss 4 days of reading every two weeks and still stay on track.
This turned out to be just the right line of thinking.
I couldn't get any reading done yesterday because just moving my eyes across the page set off the vertigo and made me have to run and puke.
When we're setting goals, we've gotta make sure we add a buffer for life, otherwise, we'll fall behind, beat ourselves up, and quit.
With that buffer, I'm still more than on track and I don't feel like a broke a "streak" because that buffer was already built into the plan.
