I don't mean to discourage anyone...but you'll find that changing careers is one of the hardest endeavors you'll ever undertake, especially if you're over 40. I changed when I was 40 and it took all my resources and some dumb luck to make it happen. Count on six months minimum of constant looking, inquiring, following leads, talking to everyone you know, following up on each lead two or three times! Don't get discouraged. For every 10 or so people you talk to, about 9 are dead ends, but that 10th one is a "guru" with many leads. It's best to start while you're still employed, which can also be difficult if you have to be discreet about the fact that you're looking. Don't forget college alumnae employment services (free) and all the good info on the 'net. The most important thing is to GET STARTED NOW. In retrospect, you'll be surprised at how time consuming all this is.
