“Is your goal to keep people on the derech, or is it so they lead fulfilling lifestyles. Theres a big big difference.”
First and foremost is that people be on the frum derech. That is more important than a “fulfilling lifestyle”. Certainly it is far far better that someone be on the frum derech without a “fulfilling lifestyle”, than have a “fulfilling lifestyle” when that is a frei-secular-irreligious “lifestyle”. Ideally, of course, is that one is frum AND lead a fulfilling life.
