How much tech did you remove. I'd imagine writing a good book would require a bit of research and stuff. At least the one you mentioned sounds like non fiction.
How much did I remove?
- Stopped using my smartphone on a daily basis. Maybe 1-2 pickups a day. Down from ~60.
- Don't play video games for recreation, replaced with working out & basketball.
- Only allow my work devices in my office. Sets boundaries for personal/work life.
- Each device has a job-to-be-done. I can only write on my laptop. I can only communicate with my phone. I can only read on my iPad. I can only work on my work machine. etc
- Got rid of most streaming services and televisions. Watch maybe a 30-60 minute show every other night.
- Turned my bedroom into a cave, no artificial light.
- When bored, I pickup a book and place them all around my house so I'm not reaching for a device.
- etc.
I, too have turned multi-purpose devices to single-purpose. I've bought some various/older devices just for this reason too. Always recommending this for folks to try
