Everyone has good days and bad days.

Sometimes, you feel as if you're on top of the world.But occasionally you feel horrible, and you lose

things and you cannot focus on your schoolwork.

For more than 20 years, scientists have suggested that high selfesteem (自尊) is the key to success.

Now, new research shows that focusing just on building selfesteem may not be helpful.In some cases,

having high selfesteem can bring bad results if it makes you less likeable or more upset when you fail at

something.

"Forget about selfesteem, " says Jennifer Crocker, a psychologist (心理学家) at the University of

Michigan, US, "It's not the important thing."

Feeling good

Crocker's advice may sound a bit strange because it is good to feel good about yourself.

Studies show that people with high selfesteem are less likely to be depressed, anxious, shy, or lonely

than those with low selfesteem.

But, after reviewing about 18,000 studies on selfesteem, Roy Baumeister, a psychologist at Florida

State University, has found that building up your selfesteem will not necessarily make you a better person.

He believes that violent and wicked (邪恶的) people often have the highest selfesteem of all.He also

said:"There's no evidence that kids with high selfesteem do better in school."

Problems

All types of people have problems.People with high selfesteem can have big egos (自我) that can

make them less likeable to their peers (同龄人), said Kathleen Vohs, a psychology professor at

Columbia University.

People with high selfesteem tend to think more of themselves, Vohs says.People with low selfesteem

are more likely to rely on their friends when they need help.

What to do

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 (药方) is to recognize

your faults, " Vohs says."It's OK to say, I'm not so good at that, and then move on."
