Recently, I’ve been following a simple rule that is helping me crush procrastination(拖延症) and making it easier for me to stick to good habits at the same time．1. There are two parts to the 2-Minute Rule…
Part 1—If it takes less than two minutes，then do it now．
2. For example，washing your dishes immediately after your meal，tossing the laundry in the washing machine，taking out the garbage，sending that email，and so on．
If a task takes less than two minutes to complete，then follow the rule and do it right now．
Part 2—When you start a new habit，it should take less than two minutes to do．
Can all of your goals be accomplished in less than two minutes? Obviously not．But，every goal can be started in 2 minutes or less．3.
It might sound like this strategy is too basic for grand life goals，but I beg to differ．The 2-Minute Rule works for big goals as well as small goals because of the inertia(惯性)of life．4. I love the 2-Minute Rule because it embraces the idea that all sorts of good things happen once you get started．
The most important part of any new habit is getting started—not just the first time，but each time．It’s not about performance，it’s about consistently taking action．
I can’t guarantee whether or not the 2-Minute Rule will work for you．5. Anyone can spare the next 120 seconds．Use this time to get one thing done．Go．
A．I call this little strategy the “2-Minute Rule”．
B．And that’s the purpose behind this little rule．
C．Here’s what you need to know to stop procrastinating．
D．Once you start doing something，it’s easier to continue doing it．
E．But，I can guarantee that it will never work if you never try it．
F．The goal is to make it easier for you to get started on the things you should be doing．
G．It’s surprising how many things we put off that we could get done in two minutes or less．
Noise-cancelling audio instruments have been around for a while now，but one Berlin-based designer believes that blocking “visual noise” is as important，if not more so，as cancelling out unwanted sounds．To this end he has created a simple accessory called the Focus Cap．
Open work spaces definitely have their benefits，but they come with the drawback of offering employees little to no control over visual distractions(干扰)．With so many people around and so much going on，some of us can easily get disturbed by this information overload and lose focus in what’s really important．That’s where the Focus Cap comes into play．
“As we are still cavemen or mammals kept in an unnatural environment，I believe that only by reclaiming(收回) the normal，stress-free human state through simple tools and techniques can we finally release our actual creative potential and create our meaningful work for a brighter future，”says German designer Hannes Greblin，inventor of the Focus Cap．
After looking at other products designed at minimizing visual distractions，Greblin decided that most of them were either too expensive or too uncomfortable to become mainstream，so he decided to go with something much simpler —a simple cap with a retractable visor(可伸缩的帽沿)．
Greblin’s Focus Cap is really straightforward．You just wear it like a regular cap’ with the sides of the visor retracted，and just collapse the sides whenever you need to focus on what’s ahead of you．Whether you’re trying to focus on a task in an open work office．Trying to study at university，or practicing yoga in a park and trying to ignore stares from strangers，the Focus Cap can help．
To be honest，this whole project sounds like a joke，but the Focus Cap does have its own website where people interested in this unusual accessory can actually sign up for updates on when it will go on sale．Greblin claims it will cost 30 euros($37)plus shipping．

2.Why did Greblin create the Focus Cap?
A. To help people focus． B. To develop intelligence．
C. To make people comfortable． D. To release creative potential．
3.What do we know about the Focus Cap?
