Deficiencies can prevent a person from achieving certain goals, as well as build effective relationships with others. If you want to get rid of the shortcomings of your personality, conduct work on yourself.
Introspection
First of all, you need to determine exactly which shortcomings interfere with your life. Try to get to the bottom and think about what qualities of your character are behind this or that shortcoming. For example, you think that you can’t be a good conversationalist because of the inability to listen to another person. The reason for this may be impatience, preoccupation with some obsessive thoughts, superficiality, egocentrism and many other character traits. Only you yourself can understand what personal qualities you should pay attention to when working on shortcomings.
You must understand that in itself a quality or several qualities that you noted for yourself can be an integral part of your personality. Most likely, you will not succeed in getting rid of them completely. Know that this is not bad. Otherwise, you would turn into another person, having lost your own personality. In addition, the same quality can bring not only harm, but also benefit.
Depending on which situation and which side to look at a particular trait, it can be positive or negative. Thrifty turns into stinginess, initiative into obsession, and so on. Thus, your goal should not be the eradication of a certain quality in yourself, but the ability to manage your condition in such a way that this trait appears only on the positive side.
