Kiruv is NOT for everyone and people should know what they are doing before getting started. Unfortunately some people push too hard and make things too difficult to keep up with. The best thing you can do for your friend is hook her up with great kiruv programs that can “turn her on” to Yiddishkeit since she already has the interest.
Something you might tell her in the meantime is how people often try to connect with nature so they shut their electronics and go into the woods just to connect with Hashem and his natural habitat and they aren’t even Jewish. They go out camping in the woods for a week at a time. How do you think they do that? They actually talk to each other, relax, sleep, eat fresh food, take long walks, read books. Hey, we do that on Shabbos too!
What about people who can’t afford cell phones, tv’s or even to pay for electricity? What do they do? Isn’t it nice to take a break from all these technologies and go back to human connections? What do other people your age do? Bikur Cholim? Visit friends? Go to shul? Read books? Take walks? Talk to family?
It is important to keep young people who are making these changes engaged in interesting and enjoyable Shabbos projects. Hatzlocha.
