I'm in a very competitive part of the country and i'm applying to 8 sites because I'm not able to move too far from home. I also truly believe in quality over quantity. When we were applying for internship, many of us started earlier and had more time to put into each application since we were not working 50+ hours doing clinical work. I worked on my internship applications for a few months. This year is different because we have very intense clinical hours and most people only start looking in Mid-November or so. Plus, i'm sure we are all BURNT OUT. I think if I apply to more sites, the quality of each application will diminish. I am confident with my decision and feel that if I do a good job on my applications, something will work out. I don't need to get my first or second choice either, and there are some options later on in the year as well if things don't work out (e.g., informal opportunities etc.). Its only a year as well so it does not have to be the perfect post-doc. I know for myself than anything more than 9 or 10 would be too much work with all my other responsibilities.
