JWs are brought up to be totally dependent on the cult leadership for everything except money.
Being a JW involves sharing a particular identity as it has developed over the years within the org. This involves acting, speaking and thinking like a JW and avoiding breaking the club rules. The trade off for believing the JW nonsense is that you get the false hope of everlasting life and a bunch of like minded friends.
However paranoid and unreasonable the organisation is, this completely human need for identity and belonging is largely fulfilled by being a JW and that's why so many are bamboozled.
So Solzhenitsyn, I suggest you might look at helping your wife discover her real self and get her to know her own potential.
Of course creativity and independence has previously been stamped on by the cult and in most witnesses the 'real person' is suppressed, often living the life of a Watchtower drudge or human doormat. Not suggesting for a moment that your wife is such but this would be the ideal personality from the point of view of the cult leadership.
So how about thinking of ways to help her realise her own dreams? Of course you will probably have to tease them out of her in the first place! There are courses in the UK called Outward Bound for example which help the timid become adventurous and most importantly self-reliant-- which is the very thing the Watchtower doesn't want its followers to be. (You could do something like this together). Perhaps encourage her to take up something she has always wanted to do for which she will receive praise because of her initiative or so that she can enjoy the results of seeing something created by her own efforts.
She needs weaning off the cult fixations and learn to fulfil her own dreams and express her own personality, and as Onager says this will have to be done with love and patience as well on your part.
