Whatever course you decide upon, there is always someone to tell you that you are wrong. There are always difficulties arising which tempt you to believe that your critics are right. To map out a course of action and follow it to an end requires courage.
无论你决定走哪条路，总会有人告诉你，你错了。总有一些困难使你相信那些批评你的人是对的。制定行动计划并坚持到底需要勇气。
