WIP Challenge Check-in, Day 21 -- Monday

[linaewen]

Hello on Monday!  What kind of a writing day has it been today -- or yesterday, if today hasn't gotten going yet?

•     I thought about my fic once or twice
•     I wrote
•     I did some planning and/or research
•     I edited
•     I've sent my fic off to my beta
•     I posted today!
•     I'm taking a break
•     I did something else that I'll talk about in a comment

Discussion - When my son writes, he can't get going properly unless he has spent time world building, both in his head and on paper.  What about you?  Do you spend time building a world before you write, or does it happen as you go along?
