Have any of you found a way to achieve anything worthwhile with only small chunks of time?
Specifically, I'd really love to do some serious reading and to make actual progress on my writing...
2. I recommend looking into the work routines of famous writers. There is a good book on the topic called Daily Rituals. Two that I recall were Hemingway, who wrote immediately when he woke up at 5:00, and Kafka, who managed to write after working his mundane office job all day.
3. In terms of learning, I really recommend looking to a SRS program like Anki, combined with list-formatted data on the topic you want to learn about. For example, if you want to learn about the American Revolution, get a PDF of an encyclopedia on the topic, then add one new encyclopedia entry per day. I do this for a variety of topics and find it much more efficient than reading long books. Using a SRS program also is the best way to make your learning time efficient.
When something is kicking around my brain, getting it out on paper takes but a moment.
Fragments of writing from fragmented times.
Immersive reading requires a time chunk.
Writing can coalesce while doing something else.
