17 أبريل 2026

Self-confidence is praiseworthy and essential to a person's success in all aspects of their life, while over self-confidence is reprehensible and life-destroying.

What is over self-confidence?

Self-confidence in its natural limits is believing in one’s confidence, and its potential and capabilities, which is positive and essential to achieving the best results. On the other hand, self-confidence, when transcending the reasonable limit, turns to the opposite and produces the consequences of the ominous!

Excessive self-confidence, blind confidence, or excessive self-pride, which is excessive self-confidence, which is not commensurate with the actual abilities and capabilities of the person, is unfavorable and leads to many failures and problems for its owner due to impulsiveness and recklessness without thinking about the consequences and without listening to anyone's advice.

Reasons for over self-confidence

There are several reasons why a person may become overconfident:

1. Nurture

The upbringing of a person, and the way parents deal with them in their childhood is one of the most important reasons for excessive self-confidence. When parents praise the child, overlook their mistakes, and applaud them for the trivial things, they grow up and feel that they are distinct from others without being objective reasons for that.

2. Illusory superiority

The belief that one is better and more superior to others and has abilities beyond their own.

3. The control illusion

A person may fall under the influence of what is known as the control illusion, which means they have superhuman abilities to control and deal with things, but in fact, they do not have any.

4. Poor planning

Some people fall into the bump of poor planning, exaggerating the amount of work or reducing the time they need to accomplish that work.

5. Wrong estimation of possibilities

A person may not be realistic or objective in estimating their capabilities and abilities, so they overestimate them, which creates a mismatch between their actual abilities and their perceptions.

6. Concealing deficiency

Some researchers in psychology believe that the origin of excessive self-confidence is significantly linked to the existence of a deficiency contract in the person. Often, those with lower competencies show the highest levels of self-confidence.

7. Individual differences

Each of us has an advantage over others, but some take great pride in themselves and fall into the bump of overconfidence because of the feature they possess.

8. Excessive accuracy

A person's over self-confidence may come from their belief that their work is 100 percent accurate, and in fact, their work may not be so!

Signs of overconfidence

Several indications in a person's behavior indicate that they are over self-confident:

Infringement on areas other than their own, as they see themselves as having the ability to work in any field.
Over self-confidence leads to a minimum of effort because the person believes that the task is easy and less than their abilities and does not need a lot of effort.

How to avoid overconfidence?

This is a set of tips helpful in avoiding falling into the bump of overconfidence:

Listen more than you speak. Whoever wants to learn and develop must listen more than speak.
Keep learning even if you are confident in your skills in your field, and don't stop developing yourself and seeking more knowledge and experience.
Open up to others, as they may have a new perspective you don't see.
Accept the mistake, take responsibility for it, and stop blaming circumstances and others.
Observe your level of self-confidence, and if you notice signs of arrogance and vanity, pause with yourself and remind yourself of the importance of humility.
Remember the passive sides of over self-confidence, and always try to avoid them.
Stop comparing yourself to others, whether positive or negative, so that you do not see yourself as better than others because of the skills they do not have. If you want to compare yourself to someone, compare yourself to who you were yesterday.
Always highlight your weaknesses and negatives, and fight the idea that you are a perfect human being.
Do not monopolize your success for yourself, especially if it is the result of teamwork, but be sure to share your success with your colleagues.
Do not exaggerate expectations, and set realistic expectations so that you do not fall into the bump of over self-confidence.
Accept criticism and feedback, especially that which is in your best interest.

Failure stories due to over self-confidence

One of the most famous stories of excessive self-confidence and its negative impact on man and his life and work:

The story of Steve Palmer (former CEO of Microsoft), whose blind confidence in his abilities, clinging to his opinion of rejecting updates, and insisting on old technologies caused the company to lose huge revenues that could have been earned if Palmer had agreed to enter the field of mobile phones.

In another story, psychologist James Reason, in the late 1980s, trying to figure out what was on the minds of the perpetrators of road accidents. Reason took to the streets throughout Manchester in the United Kingdom and asked 520 drivers to estimate how many times they had committed an offense, and what their fault was.

In addition, Reason asked them to rate their ability to lead compared to others, and if see themselves as below or above average. Reason found that of the 520 drivers, only five considered themselves below average, and the remaining 515 thought themselves above average, and this blind confidence in their driving abilities led them to risk and accidents!

In conclusion, balance is the answer!

Psychologists and researchers confirm that self-confidence is the key to success and the weapon by which we face difficulties and overcome them, but we must pay attention to the need to balance them and to have realistic self-confidence based on our actual abilities and capabilities, which pushes us forward, and accompanied by the constant desire to develop ourselves.

They warned all caution against excessive self-confidence, which is not based on reality, and inflicts a lot of problems and losses on its owner and makes others turn away from them.

The real skill is to hold this paradox, which is to combine humility and self-confidence simultaneously, as successful people have this paradox.
