Chapter 1, exercise 1.
It's been three days and I'm still looking for that quarter using the visualization method. But I've only been looking for maybe a total of an hour and a half.
Still haven't found that quarter yet, but I've stopped looking. I think that I will re-read chapter 1 and then resume the exercise shortly. I definitely need to take more walks I think but maybe I could devote a day on a weekend to walking until I find the quarter and see how long that takes.
