My ISFJ and I are incredible collaborators/teammates. We agree on so much, but the way in which we approach things is different. As a result, I think we take a very valuable comprehensive approach to our projects. I appreciate my ISFJ so much. Her sensitivity, dedication, attention to detail and thoughtfulness impresses me. Truth be told, at first her uptight behavior and high stress level was something I didn't understand and was put off by. I just pegged her as intolerant. But once I got to know her, and cast aside my assumptions, I realized how dependable and committed she was to doing good for others. And then it came easily for me to really appreciate her. I learned that she is just as sensitive as I am, and so often feels used or misunderstood. I am able to be there for her and she has been an incredible advocate for me. It can be an awesome partnership, just approach each other with an open mind
Not much to add to what Vasilisa said. It really is a team sort of relationship where there's similarity but through a slightly different approach. Course, you don't really realise this until you get to know each other much better.
Problems depend on you as an individiual.
1. People have to learn to appreciate the differences.
2. Expectations are a real pain. Idealism + Expectations is not a good combo.
I don't know very many INFJs, but they seem like incredibly cool people. Very calm, collected, and very thoughtful. The only thing that can get kind of annoying is doggedly they can stick to their idealism (which probably a somewhat unfair thing to say given that I know how doggedly I can stick to my 'realism' as well ). I appreciate their ideals and admire the direction they often think or want to go in but sometimes it strikes me as being horribly unrealistic and I can have an incredibly hard time wrapping my head around that.
Overall though, I think they're very good people

So can I...but I won't. Experiences I've had with ISFJs aren't good. But I freaking love them. they just think I'm a dreamer who can't comprehend real life. So what do they do? They modestly force it on me. Getting me into a horrible mood. And make me hate life, and I always feel guilty because it seems like I did something to deserve this. But thats just one ISFJ...
The other ISFJ is the reason why I love ISFJs. They are so dedicated and loyal to friendship, and they always apprieciate my creativity and love my unique and gentle approach to life. We are constantly lifting each other up, pushing each other to be the best we can be.
