If you’re in your 20s or even 30s, you might feel a lot of uncertainty all the time. You may be not sure what your life purpose is.1.This is normal.

We all want to have a certain life purpose. We all want to feel we’re on the right path. We all want to perfect our habits, our routines, or our productivity. We all want to feel more certain, and perfect in what we’re doing.

There is a struggle between the comfort of certainty and perfection and the fear of uncertainty and being suboptimal(不最理想的).

Let me let you in on a secret: no one is free from this struggle. Look at the most successful people you can think of —Bill Gates, Obama, Taylor Swift. 2.Do you think they have certainty and a feeling of reaching perfection? Not a chance. There is not one of us alive, not me or anyone else, who ever feels certainty about their purpose or path. If they do, they’re fooling themselves. 3.

No one ever feels they’ve found the perfect productivity routine, the perfect version of themselves. 4.

We all feel uncertainty, all day, and we all struggle with it. Some people have grown more comfortable with it than others, but in general no one likes uncertainty.

5.That’s perfectly OK, perfectly normal. Don’t run from it. Instead, stay with this uncomfortable, unappealing uncertainty. It’s here in you, a part of this moment, a part of you but not the whole of you.

A.Because it doesn’t exist.

B.Do you think they have it all figured out?

C.This uncertainty you’re feeling is unpleasant.

D.But if they’re honest, they don’t feel that certainty.

E.See if you can tell what you’re being uncertain about.

F.So focus on what you actually have right in front of you.

G.You may be uncertain about what path you should take in life.

An online map showing in real-time how busy some of Beijing's best known sites are has been designed for tourists and residents so they can plan their visits. The map, developed by the Beijing Cyberspace Administration and the Beijing Commission of Tourism Development, monitors four popular scenic spots across the capital - the Forbidden City, the Temple of Heaven, the Summer Palace and Olympic Forest Park.

People who want to visit the sites can see which parking lots have spaces free, and how crowded the venues are.

The map, at present available only in Chinese, has been designed by Sogou Inc, the Chinese search engine owned by Sohu.com Inc, and will be expanded to cover more sites across China. There are also plans to turn it into an app for smartphones.

"If there are traffic jams around these tourism destinations, roads on the map will turn red, and if visitors want to drive to the places, the map will provide every parking area in and near the spots and show a real-time monitor of empty parking lots at the same time," said Kong Xianglai, the designer and producer of the map from Sogou.

To make the information as clear and simple as possible, some buildings and streets around the sites have been removed from the map if they are not necessary, Kong said.

"Users will also see peaks in visitor numbers and where crowds are at these destinations on the map, so it is helpful for them to plan and select a travel time," he said.

After the Earthquake had stopped, when the rescuers reached the ruins of a young woman’s house, they saw her dead body through the cracks. But her pose was somehow strange that she knelt on her knees like a person was worshipping(禮拜); her body was learning forward, and her two hands were supported by an object. The collapsed house had crashed her back and her head.

With so many difficulties, the leader of the rescue team put his hand through a narrow gap on the wall to reach the woman’s body. He was hoping that this woman could be still alive. However, the cold and stiff body told him that she had passed away for sure.

He and the rest of the team left this house and were going to search the next collapsed building. For some reasons, the team leader was driven by a compelling force to go back to the ruined house of the dead woman. Again, he knelt down and used his hand through the narrow cracks to search the little space under the dead body. Suddenly, he screamed with excitement, “A child! There is a child!”

The whole team worked together; carefully they removed the piles of ruined objects around the dead woman. There was a 3-month-old little boy wrapped in a flowery blanket under his mother’s dead body. Obviously, the woman had made a sacrifice for saving her son. When her house was falling, she used her body to make a cover to protect her son. The little boy was still sleeping peacefully when the team leader picked him up.

The medical doctor came quickly to examine the little boy. After he opened the blanket, he saw a cell phone. There was a text message on the screen. It said, “If you can survive, you must remember that I love you.” This cell phone was passed around from one hand to another. Everybody that read the message wept. “If you can survive, you must remember that I love you.” Such is the mother’s love for her child!

1.Why did the leader of the rescue team decide to leave the house?
