While their work ethic is high on the ISFJ priority list, their families are the centers of their lives.
ISFJs are extremely warm and demonstrative within the family circle--and often possessive of their loved ones, as well.
In the workplace, ISFJs are methodical and accurate workers, often with very good memories and unexpected analytic abilities; they are also good with people in small-group or one-on-one situations because of their patient and genuinely sympathetic approach to dealing with others.
ISFJs make pleasant and reliable co-workers and exemplary employees, but tend to be harried and uncomfortable in supervisory roles.
In any relationship, it is love and trust that matters the most; but you never know; knowing certain quirks of your partner may help you to understand him/her better..
But the major hindrance will be during the initial stages as both partners won't be able to express their feelings.
Thus the perception, based on unworldly data, may not be true.
Needless to say, ISFJs take infinite trouble over meals, gifts, celebrations, etc., for their loved ones--although strong Js may tend to focus more on what the recipient should want rather than what they do want. They are extremely loyal to these, and are ready to provide emotional and practical support at a moment's notice.
These highly independent individuals with a strong creative streak are very charming.

It is only with great difficulty, if at all, that the ISFJ could willingly commit anyone to their doom.
Perhaps this explains why ISFJs are loyal to the end; there is no sense of purely objective (i.e., impersonal) judgement of anyone but themselves (and that only by their own standards).
I suppose it's the auxiliary nature of this Feeling, coupled with the balancing effect of that makes ISFJs tentative, conservative, and reticent to boldly state the rights and wrongs in the relational world.
