Don't idealize people. If Idealists feel sympathy for a person, they tend to attribute non-existent qualities — wisdom, understanding, and justice. Then they are often disappointed. This creates a lot of obstacles for them both in personal, friendly, and working relationships.
Personal boundaries and division of responsibility. Sometimes people of this type take excessive responsibility for other people and attribute their mistakes to their own shortcomings. Blurred boundaries sometimes prevent them from really caring about the true needs of others and, most importantly, their own.
Connection to reality. Carried away by some idea or project, Idealists forget to pay attention to everyday and organizational issues of their lives. As a result, they may neglect taking care of their health, maintaining physical fitness, eating, and drinking.
Working with facts and specifics. INFPs are often focused on some ideas, so they tend to overlook the essential details that can affect the situation. And they often get annoyed when they are given data that contradicts their picture of the world.
Self-organization. It is difficult for the INFPs to fit in with the deadline and stick to the plan. They often get carried away with new ideas, switch to them, and as a result, planned tasks are postponed.
Accept criticism. INFPs have a hard time taking criticism. Even the slightest criticism can spoil their mood for the rest of the day.
To say “no.” Idealists are extremely responsible and strive to please everyone, so their own interests often suffer.
