text: quotes .. help? these quotes that i not quite understand ... plz help "no one knews what he can do unless he tries" "the man who insists he is as good as any body" "the greatest mistake in life you can make is to be affair that you will make a mistake" 1. if you never tried to swim, for example, can you do it? you don't know, right? you'll have to try swimming and then you will know if you can do it or not. 2.the man who insist he is as good as any body talks nonsense because he would have to be as good as the best and it is o.k. but also he would have to be as bad as the worst--is it possible to be the best and the worst of all people at the same time? no, thus he is a fool. 3.the fear of making a mistake robs you from the opportunities to learn, because our mistakes are our best teachers. for example, if a new emigrant is afraid to speak a word in english  because he or she might make a mistake, they will never learn to speak the language. isn't it better to make mistakes and learn the language than to remain in this country without the communicating skills? so the greatest mistake of this emigrant can came from a fear of making a mistake.  sorry i made the explanation so long. . .
