There are certain things that we cannot make ourselves believe， no matter how hard we try.

我们需要找到方法使能源储存更高效和可持续。

The danger is not that we will be deprived of speech， but that we will have nothing worth saying.

译文：高兴欣喜之时不要轻易向其他人许诺，生气愤怒之时不要和其他人争执说话。赏析：人在情绪波动之时，做出的任何抉择往往都是错误的。人只有在心平气和之下，才能非常理性地做出选择。
