too much of a good thing

What if you have too many good applicants for a job?  Until today, based on the interviews I've participated in, I was pretty sure who I would vote for to take over my job but today we held our fifth and last (I think) interview and she was really good, so now I'm conflicted and glad that I don't have to make the final decision.  On the other hand I'm tremendously reassured that there are two good and seriously interested candidates for my job. That end of February retirement is rapidly becoming a reality.  I'm so excited.
