Steve85 - MBTI is just another system to better understand yourself and each other. Complete opposite of ESTJ would be INFP.
There are some good resources on this... 16Personalities and PersonalityHacker. Read about yourself and see if you think it's accurate description of yourself in relationships and work place. It's good to understand your own strength / weakness, so that you can become more mature and improve in those areas.
For me being INTJ... I am a thinker, and not a feeler. Any emotions I feel, I tend to want to be able to logically explain it or dismiss it. In relationships, I'm not very warn and affectionate, but I will pay close attention and remember things that you may like or need, and demonstrate it thru acts of service or gifts. So I have to work on being in touch with my feeling more, and being more in the moment rather than in my head.
I recently spoke to someone who is an ENFP... she is a feeler. If you talk to her about dates she's been on, she just tells you that most of them had no feeling, but she can't tell you logically why it was the case. I wanted to tell her that feelings can often be wrong, and that she should be more logical. But once I learned more about ENFP, I came to the realization that people are just different, and I should just understand and appreciate her.
