Honestly, I don't there is much that one person can do change the world. I like to think realistically, even though people usually see that as pessimism. Think about the people throughout history that have "made a difference". Has their impact reverberated through time, on a global level? Did they stop us from wanting to hurt and kill each other?
I just try to change things on a small scale. I try to help my friends out when I can. I pick up a piece of trash if I see it lying on the ground. I turn off lights and appliances when I'm not using them. Sure, they are small steps, and don't impact the world in the grand scheme; but they are tangible things that I can do to make my life, and the lives of those around me, a little bit better.
I like the method that i've always used, it's called *pay it forward*...i would like to believe i'm not the only one that uses this method. For example a guy knocked at the door the other day, i opend it and he said nervously that he had just got a call from his mom, saying she and his grandmother had broke down across the bay and needed him to come pick them up & help to get his grandmother on home,but he was out of gas there was no way he could make it that far with what he had,and he was without a dollar even, and could'nt think of any other way but by stoping and asking someone for help, he needed at the least ten in gas to go with what he already had in his tank, offering to leave his licence and come strate back and letting his mom repay and pick them up. I happened to have ten dollars and didn't hesitate. As he took out his licence and give me his mothers name, i told him no. Just do me the favor of remembering, he owed me. And to someday repay me by helping another when he can with that ten dollars. I like the feeling it leaves me as well,telling another how they can repay me *pay it forward*... And i know by the amount of people i've helped in that way,someone surely has done the same, you can sometimes tell by their faces that indeed it would be carried on >(by some anyway). And to me thats o.kay... So to answer this question, it would be *pay it forward* just as i"m doing,whenever i can. (my smile)
To change this world the first thing i will do is i will first washout terrorism from the world and tell all the people about the importance of unity because if we are united we can make impossible possible because impossible itself says that i m possible
