We are living our lives in a crowded world with thousands peoples ,  we all have something in common it can be the same color hair , tone of the skin , color eye , but everyone personality is different either can be good for you and bad for others or the apposite .However be yourself it can be one of the greatest accomplishments on this days.  One reason why it can be the greatest thing to be your self in this world is because the world and people behaviors is a obstacle to be you ,they would try to change you. Second reason is that to be your self , is important to find out who we are ? and what is the purpose that we want to achieve in our life thats one step. Last reason is that if you are your self the world is on your side with that you have a big weapon to make a different. Thats why I agree with Emerson statement that " To be yourself in a world that is constantly trying to make you something else is the greatest accomplishments".  The world is constantly trying to make us become something else,but the world is us humans.  One or a group or persons can be either good or bad influences to our life's .They literally can push us to do anything if we given them the control of our lives .For example in the United States we have a higher percentage of shooting in high school's and stores. The majority of them are commitment by two or more persons .The police reports that I had read, they constantly give more years in jail to the main responsible. To me one of them was a bad influence, they become a obstacle for them selves and for those that they kill. fairly both of them get to pay for what they have done .However thats why we need to know who do we call friends and family because they can push you to do things that maybe you don't want to do they become obstacle. Furthermore if you get to do anything that they want, you totally lose your self and always be the way that they want you to be .Thats why we need to find out who we are find our self ,and a purpose.  Is important that we find out who we are and what is the purpose that we want to achieve in our lives. To me in personal is hard to know everything about me, some times I do things that I never though about it. There is one phrases that is inside of me it say "If you don't know yourself how you pretend to know others". That phrases reflects to me how do we pretend to go against the world if we don't even know who we are? We basically do what we see on the world .There is violence ,murders,economical problems ,rapists,robbers, and more. In addition this include how important is to give us a purpose. It is important because if you are focus on your goal. For example you want to be a Doctor you spend a lot of time in studying and working that you would forget about what is going on in the world , you going to ignore problems and others people lives and be focus with yourself to achieve your purpose. Ones you get to be yourself the world is on your side and with that you made a different and that becomes a big accomplishment.  The personality works better when is positive and you have a good heart, you get to support others and they support you .If you have everything under control you know who you are ,and your purposes ,the world would be on your side. That makes a different to you and others,  become successful and a great influences to others. For exa
