Sigh....another of the things that JWs use to prove that whatever happens in a person's life is somehow directly connected to the manner in which they treat their association with the JW organization.
If they are trying to advance in the JWs and things go wrong, then Satan is putting roadblocks in their path to hinder them from "serving Jehovah." If they are not trying to advance in the JWs, then Jehovah is punishing them when things go wrong, or Satan is trying to deceive them if things go right. On the other hand, if they are trying to advance in the JWs and things go right, then Jehovah is blessing them.
If's all mental manipulation and coercion to try to get JWs to conform to what the WTS wants them to do.....carrot and stick.
I think that a lot of your daughter's problem is that she is buying into the whole punishment thing and is probably preventing herself from giving a good impression to potential employers. Perhaps you could suggest that she do some volunteer work in a clerical capacity at a public library, or animal shelter, or any other type of charitable group that she finds appealing. Simply offering her services a couple of hours a week would not put her in a position of feeling that she is trying to make an impression on a prospective employer, but that she is helping others...and it might help to brighten her outlook.
By doing this, she could also hone her clerical skills, and have some actual clerical experience to put on her resume. It would also show prospective employers that she is someone who is willing to pitch in and help out where necessary. It would probably also help her to dispel the guilt that her father is now trying to place on her.
Attitude is everything, and if she goes out looking for a job feeling defeated, then she is lessening her chances of actually getting the job she wants. Another positive about volunteering is that she will probably come in contact with those who could recommend her for a job. Lots of people who do volunteer work also work for companies at a regular job, and they could not only let your daughter know about available opportunities, but they could also serve as a reference for her.
