If a person can admit his incompetence and strive for perfection, he will turn out to be a good specialist. Life is dynamic, the individual must constantly replenish his knowledge base.
A person cannot be perfect in everything; there will always be people who are more professional, talented and more successful. It is foolish to strive to succeed in everything and overtake other people. This can lead to a nervous breakdown and regular conflicts. If it so happens that in a certain activity you made a mistake, then admit it. This fact will help to develop in the future, and not get stuck in some inert beliefs. As one of the proverbs says: "the smart learns all the time, but the fool already knows everything."
There are certain ways to come to terms with the fact that you cannot do something.
Experience exchange
When an individual begins to think that he knows everything and knows how, this is a direct path to regression. The most difficult thing is to learn from others and admit their incompetence to people of age.
Try to communicate more with other people, learn from them and teach yourself. The world does not stand still.
Flexibility
If you have been told that the beliefs you hold are wrong, you shouldn't be foaming at the mouth about it. Check it out, maybe it really is. However, this does not mean that you always need to question your competence, but at certain points it is worth it.
Tolerance
Be more tolerant of the mistakes of others, and people will be loyal to your mistakes.
A person learns all his life. Anyone who stops doing this begins to degrade over time. You need to be able to admit that you cannot do something.
