[Q]: Article: We like people who look like us, because they tend to have personalities similar to our own. And, a new study suggests, the longer we are with someone, the more similarities in appearance grow. Researchers set out to study why couples often tend to look like one another. They asked 11 male and 11 female participants to judge the age, attractiveness and personality of 160 real-life married couples. Photographs of husbands and wives were viewed separately, so the participants didn't know who was married to whom. The test participants rated men and women who were actual couples as looking alike and having similar personalities. Also, the longer the couples had been together, the greater the similarities. The researchers guess that the sharing of experiences might affect how couples look. The idea that there is a connection between appearance and personality might seem strange at first, but there could be biological reasons for a link, said study member Tony Little from the University of Liverpool in England. "The face displays our emotions and over time, emotional expressions may become written in the face," Little told Live Science. For example, someone who smiles a lot may develop lines and muscles that are suggestive of someone who is happy. Other studies have shown that partners who are genetically similar to each other tend to have happier marriages. The new study indicates that people have different features when using facial appearance to make decisions about someone's personality, and that the particular cues focused on change from face to face. Vital to the decision, however, are eyes and smiles. "Smiles are important social cues that may tell us whether or not someone is friendly, and eyes are also a traditional focus of attention," Little said. Overall face shape can be important too. For example, the combination of large chins and strong brow ridges can create an impression of disagreeableness and being unwilling to cooperate, Little said.

[Q]: Article: What I like to advise people is to find out what it is that makes them happy. What do you love to do? If you truly love what you do just go ahead and try to make a living by doing it. People will throw money at you to do it. But you will always have to work hard at it. I have to draw every single day of my life. I have to draw about 20 ideas. My advice is to put aside a certain amount of time every day and make you draw or whatever, especially when you don't feel like it. Only in this way will you be able to perfect your talent. The first step you take is to go to your local library and ask for the publications issued in the current years. When you get these publications, try to find the names of the top people concerned and their presidents. After you find these, write down their names and addresses. Keep this list and update it every year. Next thing you want to do is to create at least 40 cartoons. Get a grid from one of the strips in the newspapers, enlarge it to whatever size you wish and draw inside this grid. Now take the best 20 of your ideas and make them into finished pieces. To do this, you would want to copy them in ink because if you were a professional cartoonist, that was what you should do. Now you can reduce the size of the finished cartoons to fit onto a regular comic's page. By comparing yours with the others already in print, it gives you a good idea of clarity to your cartoon. The next step is to write letters to presidents of the publication. In the letters, explain who you think would read your work, or in other words, what group do you think you would target. After you complete these, send all of your information enclosed with letters in the appropriate envelope. Now as soon as you send out these letters, start to create a brand new strip with all new characters. Don't _ because if your idea gets turned down then you will give up. And always remember. If you receive a rejection from any of them, keep in mind that you are working on something better. You will be working on something new and more exciting and the rejection letter will not have any impact. With this in mind...
