If you're stuck in your writing, here's a quick method that can help.
1. Think of something that you saw or experienced today or yesterday. Then set a timer and write about it for five minutes. This is not for publication, so write whatever comes into your head. For example, this morning I read an article about how many dogs are being abandoned these days and that reminds me of a wonderful rescue dog my brother and sister-in-law had so I'd write for five minutes about that. Don't read what you've written, just put it aside.
2. Repeat for five days. Again, just for five minutes, about whatever comes to mind.
3. At the end of the week, read what you've written. What clues does it contain about how to proceed with the project you were stuck on? Assume there's a clue in there and find it. This doesn't mean that you will literally use anything from what you've written, just that it may trigger new thoughts.
Remember, during the five minute writing exercises you're not trying to make it connect to your stuck project, that only happens afterward.
Give it a try, you may find it gets you going again.
