Okay, so here is what it says about me. Much of it is true.
Supportive - the universal helpers, sharing knowledge, experience, time and energy with anyone who needs it.
Reliable and Patient – meticulous and careful, takes a steady approach to ensure that things are done to the highest standard.
Imaginative and Observant – very imaginative, and use this as an accessory to empathy, observing others' emotional states and seeing things from their perspective. A very practical imagination.
Enthusiastic – When the goal is right, ISFJs take all this support, reliability and imagination and apply it to something they believe will make a difference in people's lives.
Good Practical Skills – have the practical sense to do something with all this altruism. ISFJs can see the beauty and harmony that mundane or routine tasks can create, because they know it helps them to care for their friends, family, and anyone else who needs it.
Humble and Shy – so concerned with others' feelings that they refuse to make their thoughts known, or to take any duly earned credit for their contributions. ISFJs' standards for themselves are so high that and often downplay their successes entirely.
Take Things Too Personally – ISFJs have trouble separating personal and impersonal situations.
Repress Their Feelings – private and very sensitive, internalize their feelings a great deal. Much in the way that ISFJs protect others' feelings, they must protect their own, and this lack of healthy emotional expression can lead to a lot of stress and frustration.
Overload Themselves – Their strong senses of duty and perfectionism combine with this aversion to emotional conflict to create a situation where it is far too easy to overload themselves – or to be overloaded by others – as they struggle silently to meet everyone's expectations, especially their own.
Reluctant to Change – ISFJ personalities value traditions and history highly in their decisions. A situation sometimes needs to reach a breaking point before ISFJs are persuaded by circumstance, or the strong personality of a loved one, to alter course.
Too Altruistic – This is all compounded and reinforced by ISFJs' otherwise wonderful quality of altruism. Being such warm, good-natured people, ISFJs are willing to let things slide, to believe that things will get better soon, to not burden others by accepting their offers of help, while their troubles mount unassisted.
