Five Smart Habits of Successful Children

Have you ever wondered what actions make the most difference in your children's lives?

Children don't have to be smart to succeed. They don't have to be born rich and famous. All they need is the right outlook and a few smart habits.

Successful children make friends wherever they go. Children who learn to get along with others from an early age are more successful in life.Without them, we'd have no support. Whatever the goal, friends are needed to achieve it. Do your children a favor by encouraging social interaction early.

 2  They don't just hope for success; they are certain of it. They don't complain. They have a smile on their face and get on with the business of living. They feel pain just like the other children. The difference is that they don't let it hinder(妨碍) their progress.

Successful children become successful because they never give up. They fall. They fail. The difference is that they use their mistakes the way they were intended. They embrace failure because it pushes them forward.

Successful children ignore the naysayer (反对者). They don't worry about what other people think. They follow the path that is right for them, regardless of gossip.They are too busy working towards their goals. They do have concern for the feelings of others.

Successful children share their success. They don't forget all the people who helped them get where they were going.They don't criticize(批评) and reject(抛弃) those who are struggling. They take them by the hand and guide them up the ladder.

A.Do you want to be a successful child?

B.Social skills are vital(重要的) to human survival.

C.Successful children look on the bright side.

D.They make just as many mistakes as the other children.E. They take the time to teach others what they have learned.

F. They don't engage in gossip either, because they don't have time for it.

G. In fact, they don't even have to become rich and famous.
