“Yesterday’s home runs don’t win today’s games” “昨天的全垒打没有赢得今天的比赛”
22. Set deadlines for everything. Don’t let tasks go on indefinitely. 给所有事情都设定一个期限。不要让工作无期限地进行下去。
23. Set end dates for intense or stressful activities. Everything ends at some point. 针对时间紧或有压力的事情，设置结束时间。在某种程度上，万事皆会终结。
24. Always take notes. 多做备注。
“Get a reminder app for everything. Do not trust your own brain for your memory” 装一个提醒应用吧，有句俗话，好记性不如烂笔头。
