I took part in a writing retreat yesterday where I wrote with others in 45 minute bursts followed by 15 minute breaks. A bell announces the beginning and end of each session. It helped to have others in the room though no conversation is allowed during the writing sessions. Socializing happens at the break.
I wrote about 1900 words for The God of Trees. A good output for me. I’m not Stephen King. I don’t have the wind. Writing is like running. The more you do the better you get and the farther you can go. I think. Sounds good in theory anyway.
