3. Never Compromise Your Personal Safety.
絕不要危及個人安全。
Never put yourself at serious risk. This means that you cannot trust people until you really know them and that sometimes you have to avoid things that look like they might be fun. Never get drunk or take drugs. Unfortunately there are some malevolent people out there and it is best not to take undue risks.
絕不要讓自己處于危險的境地。就是說,不要相信還不真正了解的人,有時還要回避看似有趣的活動。絕不要酗酒或吸毒。不幸的是,這個社會總還是有不好的人,所以最好不要過度冒險。
