Remember you can't improve what you don't measure. 不进行估计也就无从改进。

If you want to improve your efficiency, you must have a baseline from which to measure. 如果你想提高效率，你必须有一个可以作为参考的标准。

Once you have a measured baseline, take a look at the different ways you can improve the time it takes to accomplish tasks or projects. 一旦有了标准，考虑你能够提高效率的各种可行方法。

Measuring also helps you predict how long tasks will take which improves your ability to schedule your time more accurately-all of which reduces stress in the process. 估测还能提升你规划时间的准确度，这都可以降低你工作工程中的压力。
