The day before yesterday, the editor replied to my new book revision comments, and I have been thinking about rewriting the beginning of the new book these days.
If you switch between writing two books, your brain won't be able to switch between them, and your efficiency will be very low.
So I usually immerse myself in writing old books for two or three days, and then focus on writing new books for two or three days.
There are still some ideas for the new book this morning that have not been implemented, so I will continue writing the new book first. I will come back to work on the old book in the afternoon, and I will update it now.
I will make sure to update it today, but don’t wait any longer during the day. Come back after 8 pm to watch it, or save it and watch it together tomorrow.
