  ▍用超速估算技巧,大幅提升你的生產力、決策力與說服力
  許多關鍵時刻的重要問題,並不是動動手指就能搞定。為什麼從Google、Apple、微軟到SpaceX面試時,都要問那些怪問題?因為,真正重要的不是答案,而是大腦思路──看面試者如何取捨眼前資訊,並找到可行方法。

  別人還在思考答案,而你,已經想出解決方案。
  「超速估算」的思考模式,就是解決一切問題的捷徑:
  ◆ 上網買東西,運費匯率加折扣,我到底有沒有虧?
  ◆ 從你家水電費,到明年的公司業績,如何掌握「遙遠」的數字?
  ◆ 利率、單位換算的超速估算法則……看出藏在細節裡的魔鬼!
  ◆ 如何不靠問卷調查,有效統計人群的意見和想法?

  大多數人都沒發覺的真相──
  ◇ 數字不代表事實,就算用數的也會錯
  ◇ 越精確,越好?「可靠」的資訊卻可能誤導你
  ◇ 你看見的數據,很多都是別人估出來的
  ◇ 數字該如何取捨?你需要知道的,其實沒那麼多!

  不管在日常還是職場,
  認真的人花10分鐘算出正確答案,
  聰明的人花10秒鐘抓出合理範圍。
  
  翻開本書,拋去計算機和繁瑣的數字,
  逐步學習「超速估算」的高效思維,
