Excellent post! I’m on the hyperactive side mentally, and sometimes have bouts of impatience while reading. It helps if the text is naturally broken into manageable pieces – – for examples, some sites allow a side-scrolling method.
On my mobile device, this basically gives me small, manageable pages one at a time, instead of a seemingly-endless vertical scroll. I can get through each page pretty quickly, which makes me feel as though my reading is progressing quickly as well, and it helps me focus less on being done and trying to get to the end of the entire thing.
