    My elder cousin Ted liked complaining almost about everything. When he faced a problem, he always chose to complain about it instead of finding a way to solve it. That was not right. Ted was healthy and had received a good education. He should and could find a good job and work hard to feed himself, but he just complained all day, drifting from one job to another. One day, I read about a farmer called Chris and told Ted about the farmer.

    Chris works hard, performs many jobs around the farm. But Chris is not exactly like other farmers. What makes him different is that he was born without arms or legs. But this has not stopped him from working hard and getting things done.

    Now, you may ask, is this possible? Like many other amazing people who have no arms or legs, Chris does not focus on what he can't do, but rather on what he can do. And he can do a lot! He drives farm vehicles and looks after crops. Once you see Chris in action, you will think there is nothing he could not do.

    Chris is a great example of a person who is making the most of his gifts. His positive attitude and courage make him a true inspiration.

    After I told Ted about Chris, he became silent. Compared with Chris, Ted was much luckier. Then luckily, I saw Ted's change.

    Do you like complaining? If you do, think about Chris. Such a man chooses to stay positive. Why don't we?
