A reminder…
When you hit a brick wall, stop and think. You can’t always go at something straight on. You need to thinkĀ outside the box. Sometimes you need to use the back door, the trap door or the chimney.
Sometimes/many times, you may never find what you want. You may need to use as much circumstantial evidence as you can to piece things together. You need to periodically look for information that you couldn’t find previously. New things are found or appear from time to time and become available.
