1. Find out what's causing you to feel inferior.
The best way to deal with a problem is to know its nature and where's it coming from in order to find a solution to the issue. For example, if the feeling being inferior come only from your mind, you might be someone who worries a lot and tends to over think, thus you exaggerate and create a false actuality. Sometimes it's other people who put you in the position where you feel inferior by criticizing and emphasizing their superiority. So finding the cause of your inferiority makes it easier for you to deal with.
2. Understand who you are.
To be able to overcome this complex, you must know what your abilities are by finding what you're talented in and accept your flaws. Embrace yourself and remember that every detail about you adds to your character. Also, you should always remember that they things you can do that many can't do, so understanding yourself will have a great deal in dealing with this complex.
3. Do not compare yourself to others.
Accept that some people are always going to be better than you at something, but this doesn't mean that you are not good at anything. Instead of comparing yourself to others, focus on yourself and try to improve every day. Always remember that practice makes perfect so always practice to improve your self and skills, by doing this people now begin to recognize you for who you are no what you are.
4. Develop a new skill.
Maybe you've been stuck for a while and you feel like everything you do is just paltry, you are not making progress and so on. Find something new, a new hobby or a skill that you could use in school or at your workplace. This might help you to realize that you are not entirely burnt out; you can gain some new perspective and boost your self-esteem and then confidence in yourself.
5. Surround yourself with people who support you.
If someone makes you feel bad about yourself, do yourself a favor and remove them from your life and replace them with positive people. Some people can help you find yourself again and make you realize that you are valuable and just as important as everyone else. Find them and keep them close, but don't forget that how you feel about yourself doesn't depend entirely on them.
6. Start telling yourself positive statements.
If you are struggling with inferiority complex chances are that your mind is programmed to continually recite your negative thoughts in your head. Try to replace those negative ideas by consciously telling yourself positive statements. This will reprogram your thought process and you'll be able to perceive yourself more positively.
