Question: Article: After my brother died in an accident, my mother was in deep sadness. I was only a four-year-old girl at the time, but I still understood the sudden shift in my mom's attitude towards safety. Suddenly everything around us was potentially dangerous. Overnight, the world had gone from a playground to a dangerous zone. I grew up with a lot of limits and rules. I couldn't walk home from school by myself, even though everyone I knew already did. I couldn't go to summer camp because what if something happened to me? As I got older, the list of things of fear got longer. My whole life was divided into "things you should avoid", and "things you needed to do in order to have a good, long life." I became a natural worrier. I worry about things like getting cancer, losing my wallet, car accidents, earthquakes, and losing my job -- disasters big and small, real and imagined. The funny part is that you'd never know it by looking at my life. In fact, I've developed a rule for myself: If it scares me, then I have to do it at least once. I've done lots of things that my mom would have worried about: I've ridden a motorcycle; I've traveled --a lot. I've performed stand-up comedy, and I'm planning my second wedding. There's something else I don't usually talk about, but it's a cornerstone in my belief: When I was 14, my mother died suddenly in a car accident. At my mom's funeral I remember making a choice. I could either live out the rest of my life trying to be "safe" or I could be brave enough to live out a fulfilling, exciting and, yes, sometimes dangerous life. I worry that I may have betrayed my mother by writing her in this light, but she has been a driving force in my life and, in the end I think she would have been proud of me. Courage isn't a natural character of human beings. I believe that using courage is like developing a muscle. The more often I do things that scare me or that make me uncomfortable, the more I realize that I can do a lot more than I originally thought I could do. Even though I inherited my mother's cautious nature. I've also come to believe that fear can be a good thing, if we face it. Believing that has made my world a less scary place.

Question: Article: I come to the United States ten year ago. I would always say that I was trying to study, but there were always things like work and my kids that would not allow me to start. Now I realized that those were only excuses. What stopped me was that I was afraid to start studying again. I always believed I would learn by myself. One day, however, my son told me that he was sad because his friends would come over and I didn't understand them because I didn't speak English. He was also sad because I could never help him with his homework. That same day, I told myself, "Rocio, you have to start believing in yourself and you will see you can make it." The next day, I went downtown to look for a big banner in front of the school which said that they offered classes for adults. I came in to see if I could join, but the classes were closed already. That night I took the kids to the movies, and on the way back, I told them we would take a new route. I ended up getting lost. That's the way I found Chaffey College. The following Monday, I went to ask for information. They told me that summer school was starting that week. That's how I started studying English last summer. It is difficult, but I have had great rewards. My daughter had to write a story for school. It was about the female they most admired and why . She wrote that I was the person she most admired because I had started going to College. I will never forget this.

Question: Article: The Big Brother in the novel 1984 listens to everything and nothing can escape his ears . Now in reality , we have Facebook . The social media giant has never denied that it's keeping track of conversations you have near your phone ( if the Facebook app is open , that is ) , but not , one expert has told NBC that Mark Zuckerberg's empire may be keeping ears on you at a more regular basis . According to Professor Kelli Burns , who teaches mass communication at the University of South Florida , it may be listening more often than it lets on . To prove her point , Burns turned on the microphone feature on her phone , and said , " I'm really interested in going on an African journey . I think it'd be wonderful to ride in one of those jeeps . " Less than a minute later , when she checked her Facebook page , she was met by a story about a journey - the first post on her newsfeed . There was also a car ad on her page . While Facebook says that it's only keeping its ears open to help " identify the music you're listening to and TV matches you're watching , " Burns' little experiment suggests that there may be other motivations at play as well . But the social media company has denied claims that it records any conversations , and told The Independent , " Facebook does not use microphone audio to inform advertising or News Feed stories in any way . Businesses are able to serve related ads based on people's interests and other statistic information , but not through audio collection . " Whether you believe this statement or not , there are ways to stop Facebook from listening in at all . Simply turn off your phone's microphone by heading over into Settings ( if you're an iPhone user ) , going to the Privacy tab , then clicking on Microphone . From there , you can remove Facebook's mic privileges , and probably , stop the company from hearing your conversations . On Android , you can also go to Privacy under the Settings tab , and change Facebook's permissions . So the next time you're chatting with your friends about your summer vacation plans , keep an eye on your Facebook feed . There may be more participants in your conversation than you realize .
