Over a decade ago, I wrote a guide to world-building. It took about 15 minutes each day over the course of 30 days, and if you did it in October, when NaNoWriMo started on November 1, you'd be all set with a world you could write in.
Well, in 2017: I'm bringing the world-builder guide back! The old guide is still available, but this year, I'll be posting each day's exercises on Steemit, updated and refreshed for this new release, and with the tag #thirtydayworldbuilder.
If you want to participate, read the post (hopefully upvote it!), do the exercise, and if you want, you can post your exercise there as a comment on that day's post, or post it to your own feed and maybe link back here.
Hope to see you back here on October 1!
