Challenges of life are of great important in our growth. It reminds me of my days which I joined in the military training after I entered senior high school. It was the first time I have lived away from my home, so I found difficult to fit in. And the training officer was strict on me. I once thought I couldn’t stick to the end. But final, I made it. The training made it much easy for me to adapt to my future life. And the difficulties I came across have now became a precious memory in my life.

In a short, it’s better to learning to regard the challenges of life as the stepping stone to future success and make the best of them.

   Blind people can read. They do so by running their fingers along a line of raised points or dots on paper. Of course, they first have to learn the code（代码）. Here are some examples of it. One dot stands for the letter “A”. Two dots side by side mean “C”. Four dots arranged to look like a box（：：） stand for the letter “G”. By placing the dots in special patterns, all the letters of the alphabet can be formed.

This code was made up by a Frenchman called Louis Braille. Though he could see at birth, he became sightless when he was only three. Braille was cutting leather in his father’s shop. His knife slipped and cut his eye. Infection（感染）spread to both eyes, and he became blind.

At 10, he was placed in a home for the blind. But young Braille had great talent. He became a skilled musician and soon got a job as a church organist（风琴弹奏者）in Paris.

Because he had talent and was quick, he became a teacher at a school for the blind. While there, he heard that a captain had sent messages to his soldiers that they could read at night without light. His messages were in the simple form of raised dots and dashes. This was the clue Braille needed. At the age of 15, he worked out his own six-dot code. Each group of dots is called a cell. The cells are three dots high and two dots wide. For the rest of his life, Braille taught his young flock to read both written and musical works using his code.

For the last 17 years of his life, Braille was ill with tuberculosis. He died at the age of 43.

   Ryan Hickman is only seven years old, but he’s already been saving for his college fund with profits he’s making from his recycling business.

When Ryan was three-and-a-half, he went with his dad to the local recycling center and made money from a few bags of cans and bottles. When he learned money can be made from that, Ryan decided recycling was his future.

“We had gone to the center with a couple of bags, and he really loved the actual act of putting all the cans and bottles into the machine and getting the money from it, and that kind of act got him hooked, ” described Damion Hickman, Ryan’s father.

Ryan told his parents that he wanted to give empty plastic bags to all the neighbors and hoped they would save their recyclables for him. Not only did the neighbors save their cans and bottles for Ryan but so did their co-workers, families, and friends. Soon after, Ryan started his own business, Ryan’s Recycling, and has since recycled over 200,000 cans and bottles. Every week, he and his family sort through bags of recyclables and they take them to the local recycling center where they are sorted and weighed.

So far, Ryan has saved more than $ 10,000 for college from his profits and he also sells T-shirts on his website and donates the profits to the Pacific Marine Mammal Center in Laguna Beach. “For the sea lions to get food and medicine,” he said.

Ryan has an important message for everyone, “If you already recycle, just keep on recycling. If you don’t recycle, start recycling.” Always a great businessman, Ryan added, “If you want to buy one of these T-shirts, it’s $ 13 on ryansreecycling.com.”
