On-The-Spot

I don't know why I'm doing this. I'm busy, a full-time writer who just signed up to a website about writing out of curiosity, and moments later I'm taking a challenge! Well, free-writing has always been a fun exercise for me, and sometimes I actually get decent stuff out of it. Well, I'm not sure what to write next. Something creative, perhaps? I could try to do an on-the-spot sonnet, which would annoy anyone reading this and turn many others off. People don't like sonnets these days, and most of the modern ones aren't much good anyway. Maybe I could start a story, but, well, now I'm out of words!
