I always like to look on the optimistic side of life, but I am realistic enough to know life is a complex matter.

Optimism is a learned skill.

People are afraid to pursue their most important dreams, because they feel that they don't deserve them, or that they'll be unable to achieve them. We, their hearts, become fearful just thinking of loved ones who go away forever, or of moments that could have been good but weren't, or of treasures that might have been found but were forever hidden in the sands.

一个好的战略不仅仅是敦促我们朝着目标或愿景前进。一个好的战略诚实地承认所面临的挑战，并提供克服这些挑战的方法。

Everyone seems to have a clear idea of how other people should lead their lives, but none about his or her own.

解析：不要窃取他人的成果，不要忘记自己的耻辱。
