Don't fret. We all occasionally sit staring at something for a long time only to see (or have pointed out to us) the most simple, obvious solution. It seems like you often spot the solution yourself only after asking someone else -- and I suspect that is not coincidence. The act of explaining the problem to someone else forces you to view the problem somewhat anew.
