A well-run career search campaign doesn't necessarily have to be fun to be successful. It's like exercise. Sometimes exercising is fun, sometimes it's not. It isn't always comfortable. But then, comfort isn't the goal.
Physical fitness is the goal.
The goal in exercising is to do it to the best of your abilities and physical condition and be disciplined enough to do it regularly, regardless of whether you are having fun or not. If you want to get or stay in shape, you have to exercise. In the same manner, networking isn't always comfortable. But then comfort isn't the goal either. Getting a really good job is the goal.
