Question: Article: Dad was always full of advice, but one of the biggest lessons he taught me one summer was about having a strong work ethic . When my brother and I were growing up, we mowed yards during the summer to earn pocket change. Dad was our salesman. He told our neighbors about our service and offered a price they could not refuse. My brother and I got $ 10 per yard. I later found out that our friends were charging $ 20 or more for the same amount of work. Every time we headed out to mow lawns , Dad was there to watch. I used to wonder why he came with us. He stood supervising our work in the heat when he could have been inside relaxing with air conditioning and an icy drink. One day we were cutting our next-door neighbor's yard, he always waited until the grass was knee-high to call us over. To make matters worse, we had an old lawn mower. This particular afternoon, I was finishing up and was tired and sweaty. I was just about to cut off the lawn mower when I saw Dad pointing to one piece of grass. He yelled, "You missed a piece." I frowned, hoping he would let it slide and let me go home. He kept pointing. So, tired and disappointed, I went back to cut that piece of grass. I said to myself, "That one piece isn't hurting anyone. Why won't he just let it go?" But when I reached adulthood, I understood his message ---When you're running a business, the work you do says a great deal about you. If you want to be seen as an entrepreneur with honesty, you must deliver a quality product. That single blade of grass meant the job was not done. Other neighbors took notice of the good work we did and we soon got more business. We started out with one client, but by the end of the summer we had five.
Answer: They mowed it carefully.

Answer: Why did more and more people ask the brothers to mow their yards?

Question: Article: For a long time people have believed that high self-esteem is the key to success. However, new research shows that focusing just on building self-esteem may not be helpful. In some cases, having high self-esteem can bring bad results if it makes you less likeable or more upset when you fail at something. "Forget about self-esteem," says one of the psychologists involved in the new research. "It's not the most important thing." This idea may sound a bit strange to you because studies also show that people with high self-esteem are less likely to be anxious, shy, or lonely than those with low self-esteem. In short, to feel good does you good. But, after reviewing about 18,000 studies on self-esteem, Roy Baumeister, a psychologist at Florida State University, has found that building up your self-esteem will not necessarily make you a better person. He believes that violent and evil people often have the highest self-esteem of all. He also said, "There's no evidence that kids with high self-esteem do better in school." All types of people have problems. "People with high self-esteem can have big egos that can make them less likeable to their peers," said Kathleen Vohs, a psychology professor at Columbia University. "People with high self-esteem tend to think more of themselves," Vohs says. People with low self-esteem are more likely to rely on their friends when they need help. Researchers say it is best to listen to and support other people. Find positive ways to contribute to society. If you fail at something, try to learn from the experience. The best therapy , as they suggest, is to recognize your faults, accept yourself, understand your weaknesses and then do something about them.
Answer: New research shows that high self-esteem may not be helpful.
