Abandoning the doctrine of “juggling your life” and making the alternative move into simple life brings far greater rewards than financial success and social status.
句意为：放弃“为生活忙碌”的信条，转而过简单的生活，带来的回报远远大于经济上的成功和社会地位。
故本句的主语为Abandoning the doctrine of “juggling your life”、making the alternative move into simple life。
所以本题选AB。
