I've found explaining the situation to another person helps. Usually having to make coherent statements about a thing causes me to realize what I am failing to put together. Also, often whatever obvious thing I am failing to see stands out clearly to someone with fresh eyes. Those eyes could be someone else's. Or they could be your own. Did you know that the human eye constantly moves around even when its staring at something? If it didn't, the same exact stimulus would eventually be invisible to it. They've held eyes completely still in the lab and kept the stimulus the same and eventually the eye stops seeing anything. The same thing can happen to your attention when it constantly focuses on a problem.
