I think the best actors are the ones who are willing to take risks and not be afraid to fail.
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.
Gain wisdom through reflection.
不过是君主不把它[爱人利人]用在政事上,士大夫也不把它付诸行动罢了。
