YSK When a succesful businessperson claims to work 16 hours a day, the "work" often includes things like business lunches and golf with clients. Don't try to match them by doing actual work for 16 straight hours, the human brain can't concentrate that long and it will just be counter productive.

當一個成功的商人聲稱每天工作16個小時時，"工作 "往往包括像商務午餐和與客戶打高爾夫球這樣的事情。不要試圖通過連續16小時的實際工作來與他們相提並論，人的大腦無法集中那麼長時間，這樣做只會適得其反。
