I write in blocks myself. My modus operandi.
1. I start with three four books at any given time.
2. I have a Google Drive file called “book ideas” for any particular topic.
3. As ideas hit me, I just update that particular file.
4. Writers are moody people and the right mood can really make a difference. I wait for the right mood to come. When it comes, I go for long hours to write my chapters. Sometimes, I write whole day and other times I don’t write for days.
5. I always churn up topics to avoid boredom. I have varied interests ranging from mathematics to writing to arts to any thing.
6. I don’t have any set time to write, or any deadlines. I write without pressure.
