The best way to get new insight into a problem is to get away from it. Put that “brick wall” away and do something totally unrelated to your genealogy for a while. Sometimes the mind simply needs to let things stew for a while. If you just can’t put your brick wall away, then work on another problem.
Personally I have the best breakthroughs when I walk the dog and discuss my problem with him. He never interrupts or criticizes and it gives me time to really think. Sometimes criticism is good, but one needs time to organize your thoughts and put them in order.
Constantly researching non-stop does not allow that to happen.
Riley is one of the best brick wall breakers I have.
