INTJs and ENTJs might be at opposite ends of the Introvert/Extravert spectrum, but what they have in common is a drive to solve problems. This is great for building careers, but when it comes to friends, family and colleagues, their delight in giving advice can ruin relationships.
If you are an INTJ or an ENTJ, you may already know that you have a tendency to express your thoughts and opinions quite openly. But have you considered the effect this has on other people? And that your need to give unsolicited advice is probably caused by a lack of self-confidence.
