I think I've mentioned here before that I try to go for a walk every day around lunchtime. It gets me out of my office and into the sunlight, stretches my legs, gives me a modicum of exercise, and forces me to stop thinking about work for a few minutes. I've found that these are all good things, and since I work practically nonstop during the day, I've also found that they are necessary for my sanity.
There's a certain tree along my typical walking route that I stop by almost every day. One might say it's my inspiration tree. Every time I set out with a topic on my mind, or a particularly difficult problem that I was stuck on, I find myself stopping at this tree and furiously typing ideas and notes into my phone.
The thing that interests me about this, is that I seem to stop at the same place every day. I know it's not the tree that is the cause of my inspiration, because it only serves as a convenient place to stop under without looking completely preoccupied to other passersby. So, it must be that the act of me intentionally going for a walk to work on a problem, coupled with the physical exertion (however slight), and approximate distance of the tree from my starting point.
So, this may not be anything more than anecdotal evidence for problem solutioneering, but I have found it to be an effectual ritual. Perhaps you will as well.
