我们需要时常回顾，反复总结我们的经历、作为、经验，以及从中获得感受，对比我们当时的判断与目前的判断，把我们的志向及努力，与结果以及由结果得到的满足加以比较。We need to review and summarize our experiences, actions, experiences and feelings from time to time, compare our judgments at that time with our current judgments, and compare our aspirations and efforts with the results and the satisfaction obtained from the results.——Arthur Schopenhauer
