Four things you’re doing which seem productive (高效的), but aren’t.

In the busy world of work, most of us have tried some ways to help us get things done more quickly. 【小题1】

•Working without taking short breaks       

When you make plans, short breaks should always be considered. After long working hours, you can have a short break of paying attention to something totally different. 【小题2】

•Keeping your plan in your head       

If you don’t write down what you have to do, you may save some time. 【小题3】 So it would be much better to write everything down and deal with each task one by one.

•Saying “yes” to everything       

Saying “yes” is much easier than saying “no”, but if you say “yes” to everything you will soon feel stressed. 【小题4】 You will achieve much more by the end of the week.

•Putting the most difficult task at the top of your list       

Doing this does not mean you can finish that task on time. In fact, it’s possible that you will still put it off, as it will only make you more worried about it. 【小题5】

A．However, some may not be so helpful as we think.

B．The problem is that you may also forget them easily.

C．It’s better to only do a few projects and do them well.

D．For example, listening to music or taking a short walk.
