When you meet someone for the first time, you will get a quick idea in your mind of that person in the first moment. Your feelings about other people, however, are really just show the way that you look at yourself.

    So you can allow others to be the mirror to see your own feelings of self-worth more clearly. And, you can see the people you don't like as mirrors to show you what you are not accepting about yourself.

    To live peacefully with others, you will need to learn patience. A big challenge is to let your judgment of others be a lifelong research of yourself. Your task is to consider all the judgments you make onto others carefully and to begin to see whether you can use them to help yourself to become better.

    Several days ago I had a business lunch with a man who showed objectionable table manners. My first feeling was that he was impolite. When I noticed that I was judging him, I stopped and asked myself what I was feeling. I discovered that I was nervous to be seen with someone who was eating with his mouth open.I was very surprised to find how much I cared about how the other people in the restaurant judged me.

    Remember that your judgment of someone will not stop you from becoming like him. Just because I think my lunch partner impolite, it does not prevent me from looking or acting like him. In the same way, my patience to him would not make me eat food with my mouth open.

    When you get close to life in this way, those whom you hate and those whom you love can be seen as mirrors, guiding you to discover parts of yourself that you dislike and to accept your greatest personalities you are proud of.

    Sometimes you'll hear people say that you can't love others until you love yourself. Sometimes you'll hear people say that you can't expect someone else to love you until you love yourself. Either way, you've got to love yourself first and this can be tricky. Surely we all know that we're the apple of our parents' eyes, and that our Grandmas think we're great talents and our Uncle Roberts think that we will go to the Olympics，but sometimes it's a lot harder to think such nice thoughts about ourselves. If you find that believing in yourself is a challenge, it is time you build a positive self-image and learn to love yourself.

    Self-image is your own mind's picture of yourself. This image includes the way you look, the way you act, the way you talk and the way you think. Interestingly, our self-images are often quite different from the images others hold about us. Unfortunately, most of these images are more negative than they should be. Thus changing the way you think about yourself is the key to changing your self-image and your whole world.

    The best way to defeat a passive self-image is to step back and decide to stress your successes. That is, make a list if you need to, but write down all of the great things you do every day. Don't allow doubts to occur in it.

    It very well might be that you are experiencing a negative self-image because you can't move past one flaw or weakness that you see about yourself. Well, roll up your sleeves and make a change of it as your primary task. If you think you're silly because you aren't good at math, find a tutor. If you think you're weak because you can't run a mile, get to the track and practice. If you think you're dull because you don't wear the latest trends, buy a few new clothes. But remember, just because you think it doesn't mean it's true.

    The best way to get rid of a negative self-image is to realize that your image is far from objective, and to actively convince yourself of your positive qualities. Changing the way you think and working on those you need to improve will go a long way towards promoting a positive self-image. When you can pat yourself on the back，you'll know you're well on your way. Good luck!
