A friend is better than fortune. A friend is worse than poison in some cases. 
The two sentences above have opposite meanings and seem to be unreasonable, but they can be explained as follows: the first refers to all good friends who drive us towards good while the second all bad ones who lead us into bad ways.
　　My ideal friend is of course a good friend whose goodness is shown below — he has no bad habits, such as smoking and drinking. He lives in frugality (节俭). He studies hard so as not to waste his golden time. At home he honors his parents and loves his brothers; at school he respects his teachers and shares the feelings of his classmates. He treats those truly who are true to him. In a word, he has all the good characteristics that I don’t have. I can follow him as a model. With his help I can be free from all difficulties.
Indeed, if I have such a person as my friend, I shall never fear difficulty and I shall never know the existence of the word “failure”.
