There are many reasons for self-doubt, mostly they come from childhood. Both overprotection on the part of the parents and rejection can lead to this. Psychologists have several recommendations on how to get out of a state of insecurity.
Recognize your uniqueness and stop comparing yourself to others. Such comparisons only exacerbate uncertainty: one has excellent communication skills, another has a lot of money, the third is always relaxed. Comparing yourself to others, you will accumulate so many "competitors" for yourself that you will fall into ultimate despair. Because it is impossible to surpass everyone and in all respects. Pay attention to your strengths and talents and focus on them. You, too, have something that others might envy. So develop it and feel free to show it!
Give up the habit of self-flagellation. Too many people consider self-criticism to be the best motivation. But being negative about yourself constantly doesn't help your self-confidence. Criticism is sometimes really helpful, but without self-deprecating statements. If you made a mistake, better think about how you can fix it most effectively. And it is better to motivate yourself to action, focusing on your merits. For example, think about how well you did the last time.
Stop agreeing with everything, and then suffer - after all, you need to fulfill what you agreed to. Out of healthy selfishness, give up the things you don't feel like doing.
Accept praise with dignity, without responding with phrases that deny your importance. In many cultures, courtesy rules recommend responding to a compliment with something like "you're too kind" or "okay, I didn't do anything special." With these phrases you belittle your achievements and merits, unconsciously putting yourself down. The interlocutor will also interpret this message in this way. Say thank you, don't be shy. After all, there really is something in you that deserves gratitude and admiration.
Quite a banal recommendation, but auto-training has not harmed anyone yet. If you repeat different encouraging phrases from day to day, they will really take root in your mind. The benefits of self-hypnosis have been proven for a long time. And together with other ways to increase confidence, it will definitely give a good result. You can repeat phrases invented by yourself or ready-made. For example: "I am a confident person", "I deserve the best." Repeat these phrases when in doubt. And to find more meritorious virtues in yourself, make a list of achievements.
Don't dwell on theoretical considerations. Get started! Take on challenges from the world around you. This will help you gain respect from yourself and others.
Surround yourself with open and positive people who will honestly talk to you about your strengths and weaknesses. Avoid individuals who like to judge and criticize others. They will overwhelm you. In turn, become more interested in people. Help them, encourage them and they will answer you with gratitude. And gratitude will make you feel worthy and raise your mood. You will find that you can help someone become happier.
Learn to listen to your inner voice, no matter what crazy things he says. A lot of things people do under pressure from any authorities and society. They enter the wrong faculty, marry the wrong woman. As a result, the feeling of dissatisfaction remains, the person does not feel “in his place”. There will be no self-respect and no understanding of the meaning of one's own life. So, stop doing what others want and start your own life.
