Do keep a thesaurus, but in the shed at the back of the garden or behind the fridge, somewhere that demands travel or effort. Chances are the words that come into your head will do fine, eg “horse”, “ran”, “said”.

Well actually I was at home. I was doing some housework. So I was very surprised.

Keeping all devices aside 1 hour before sleep, stopping all work chats at Zerodha unless critical after 6pm, and spending time doing what is most relaxing just before sleep (spending time with my son & hobbies) and on weekends has helped me the most with sleep.

Have more than one idea on the go at any one time. If it’s a choice between writing a book and doing nothing I will always choose the latter. It’s only if I have an idea for two books that I choose one rather than the other. I ­always have to feel that I’m bunking off from something.

Being willing to listen to my ideas and tell me when they are good and when they are dumb.

The inventor of the modern zarf. “Zarf” is the name of the cardboard sleeve that goes around your coffee cup and keeps your fingers from getting burnt. I love the little masterpieces all around us that we take for granted. By the way, zarfs have a long history — there were gold and tortoise shell zarfs back in ancient China. But the modern zarf was created in 1992 in Portland by Jay Sorensen. It’s called the Java Jacket. Thanks Jay!

So words are my true love. But I grew to love all these other genres, including jigsaws, which I was very snobby about and looked down on. I was, ‘They’re not real puzzles.’ But I am a reformed jigsaw skeptic. I can officially say I am now a jigsaw lover.

Well, I’m in the midst of writing 1,000 handwritten, personalized thank you notes to readers of my books. It’s simultaneously a major pain in the butt — it’s taking me several weeks — and also delightful. I feel like I’m getting to know the readers of my books, which is great, since writers often have a solitary existence.
