Regret for the things we did can be tempered by time; it is regret for the things we did not do that is inconsolable. 若后悔既成之事,时间方可平抚,但若懊悔未竟之事,则永远无法缓和。 Sydney J. Harris
A positive mind finds a way it can be done; A negative mind looks for all the ways it can't be done. 积极的人会去寻找任务的解决方案;消极的人会去寻找无法完成任务的各种理由。 Napoleon Hill
Failure after long perseverance is much grander than never to have a striving good enough to be called a failure. 相比未有过可称之为失败的努力,坚持不懈之后的失败要伟大得多。 George Eliot
