How can I develop self-confidence and self-esteem?

Develop self-confidence:                                                                  To most of my acquaintances I am a rude,disobedient and self-respecting person.That is why I get rejected by some of my friends, relatives and even neighbors.But the real thing is that even after this receiving this rejection, I am so overwhelmed.How can I be so hard-hearted? How can I live a comfortable life, ignoring thousands of such attacks.                            Here's how I managed to make it this way-                           1.Represent yourself:    Present your character i a slightly different way. Make yourself believe that you can compare yourself to your friends and few others if you want to. And you can pass as the best. Make life your choice, there is no need to regret reaching the end of life. Encourage yourself more in what you are interested in. Accept yourself, because if you accept, everyone will accept you. Be confident, so that you can gain everyone's trust.                                 

 2.Debut to yourself:    Build a positive character for yourself. Achieve what you want, because what you think of yourself is manifested in your brain. So think of yourself as successful before you can achieve success.                                                 

                                                                                   3.Become a warrior:  Choose a job that is not  as simple  as some of them. Choose a job that you have never thought of doing. Do not give up even if it is in vain, your effort are inspired without anyone pointing a finger at you.                                                                                                                                                                                             4.Turn around:   Don't give up on life. Keep yourself happy, build the days in such a way that the word 'boredom' becomes unfamiliar to you. There is so much in life to keep yourself excited just waiting for you to find it. Coming means your self-esteem, willpower are declining. Spend time with yourself. For those who are usually self- respecting,  life is very precious to them, they don;t miss a single moment, they enjoy all the time.                         

  5.Build yourself up alone:  Learn to be self-reliant. Do your own work without any help. Do it yourself without getting involved in small things in vain, take the initiative on your own. Build yourself differently from everyone else. When you start looking for your world alone, you will find it. see with a new eye of self-confidence.                                                                                                 So according to your question you can develop your self-confidence and self-esteem only when you practice it in the face of rejection, humiliation, criticism and negative words from people.                                                                                                                                     [ And believe that people will call you superhuman]                                                                                                                                                 Thanks.
