There are three types of people who are not flexible:

Firstly, people who have absolute confidence. Due to their absolute confidence, they tend to be subjective and biased, making it difficult for them to communicate and coordinate with others or cooperate with them. Therefore, they often get stuck in difficulties and deadlocks at work, and their lives lack the space for growth. As a result, they are not good mentors or good friends.

Secondly, lazy people.

Thirdly, people with extremely slow reactions.

How can we determine whether someone is an absolutely confident person?

1. High ears, high nose, and high brow bones:

People with these features represent intelligence, alertness, and high comprehension ability. They have strong desire for control and domination. Their lives are full of ideals and ambitions. They are unlikely to admire others or submit to others. Over time, they tend to become self-righteous people.

2. Loud, high-pitched, and hurried speech:

This represents the desire to suppress others, without considering others' opinions or the surrounding people and events. Eventually, they tend to become people who are stuck in their ways and resistant to change.

3. Eyes that look restless or fixed:

Fixed eyes indicate subjectivity and persistence. They are not easy to accept others' opinions or change their own ideas. If they look like staring, it is a trait of an extremely uncompromising person.
