Re: Perhaps chasing windmills?
Thats a reasonable thing to consider in a good economic climate, but we are in a recession with loads of people out of work. Double the contention in my field means there's also double the contention in related fields - half the people going after MY jobs are those who are looking at closely related fields to their own! If you have a choice of 20 people, of whom 10 are specialists in the relevant field & the other 10 are from a similar field, you'll only bother looking at the specialists at exactly what you want.
Yes hard work & emotional investment, sort of used to it now (sigh).
