For example: Give yourselves one hour to write a short story.
That's what my pal and I have been doing since 2020. For awhile, we did it every Wednesday. There were periods of burnout where we did it just once every few weeks/month. At other times, we've done challenges were we did it everyday for a month (that's our practice this month of Feb). We usually audio record what we've written and share it with each other via Whatsapp (he lives in the UK).
It's a beautiful, sometimes daunting, practice. I've amassed a google doc with 100,000+ words just by showing up to do this. It's never about quality, more just a method of working things out. :-)
