For decades, a billionaire Ray Dalio has communicated with some of the most successful people in the world. Along the way, he’s________a thing or two—including a habit that the “who’s who” are just better at than the________person.

“________,” Dalio tells CNBCMake It, “the most successful people are really much better at knowing their________.” In fact Dalio believes if you don’t know your weaknesses, you can’t________them. “So how do you________out your weaknesses?”

Dalio says daily feedback from those around you, like your boss and colleagues, is a good first________. You can also notice patterns in the________you make. And while most people have several weaknesses, it’s important to find your “one big________”, which is the weakness that is the biggest________to getting what you want. Dalio writes his weaknesses down and________them where he can see them every day so he is________of what he needs to work on.

Once you find out your big weakness, talk to others about it to________more information and find ways to turn it into a(n)________. An easy approach is to find people who are more________in that area, whether that’s a colleague, a coach or a friend. “You don’t have to know________,” Dalio says. “You just need to work with people who are________where you are weak.”

Since Dalio, who turned 72 years old on Sunday,________down as co-CEO of Bridgewater Associates in 2017, he says he has been focused on helping others________through Principles, a people management software________he founded.

Last February I turned 51. And to be honest, it didn’t make me jump with_______.

Of course, I still_______the face in the mirror. But it certainly didn’t_______my inner me anymore. There are many_______about age-enthusiasts who_______a whole new job? accomplished extraordinary achievements or trained to run a marathon._______they didn’t quite inspire me. It only_______me even more.

Until, three weeks ago, I came across Face App. The app has_______my husband to an 88-year-old man, wow! My husband took my picture and put it into the app. It caught my_______and showed an 88-year-old version of me with deeper________. My teeth were shorter. My neck was seriously sagging (松弛). I________the picture with such a sharp eye that it ________ burnt a hole through the screen. But then I zoomed out and looked at the ________picture. I saw softness on the cheeks; the comfort of a warm smile; a look with a lifetime of extremely rich________. That night I shared both my present and ________me on Facebook. My friends seemed to________the old me. “I think you look pretty cool,” one commented.

Again I studied the older face carefully. Suddenly I felt I________back at that older lady who might be me. I haven’t run a marathon or started a new cool job. My jump forwards is a purely emotional________.I've opened a door within myself and behind it________appreciation and love for myself, regardless of my________. Now, when I see myself in the mirror, I’m sincerely pleased.

I was living in Cali, Colombia. One day my younger sister decided to visit me for a holiday and I was supposed to go to meet her at the airport. I somehow lost ________ of the time and realized that I was ________my home much later than I had wanted to. And to make matters _________, when I went outside, the rain was pouring from the sky and I couldn’t get a taxi to save my life. I ________ jumping on board a public bus to Palmira, where the airport was .

The driver said that I would be dropped ________ at a crossroads which was located six kilometers away from the airport. I had no ________ but to travel with the bus. The journey took ages, however. When the bus did eventually ________ the previously mentioned crossroads, the driver pointed in a given ________ and told me that the airport was down that way. By this time, I had descended into tears. My sister would be arriving in twelve minutes, and there was no way I was going to be able to make it ________. Beside myself (失去控制) with worry, I ________ the driver to drive the six kilometers down to the airport to drop me off. He stood up and took a vote from the other passengers. Fortunately, they all ________. Thanks to them, I arrived on time. This was my first encounter with Murphy’s Law (墨菲定律): Whatever can go wrong will go wrong. And the only way to beat this devil is to take ________for the outcome of all your actions. I should have made a Plan B by ________ the possibility that there would be no taxis available. Of course, some major victories were achieved by the very fact that they did not have a Plan B to ________.

However, most of the situations we encounter in our lives are much less dramatic and can often be ________ in more ways than one. It is ________to have a Plan B because you cannot always guarantee that your original plan is going to work out, and in some cases, your contingency (不测之事) plan might just be even ________ than your original one .

Now more than ever, in this rapidly changing world, ________ is often the key to success. If you are prepared to bounce back when everyone else ________, you will be the winner. Think of your contingency plan as a form of ________, one that, if nothing else, can give you the peace of mind you need.
