     A popular saying goes, "Sticks and stones may break my bones, but words will never hurt me."

However, that's not really true. Words have the power to build us up or tear us down. It doesn't matter

if the words come from someone's else or ourselves -the positive and negative effects are just as

lasting.

     We all talk to ourselves sometimes. We're usually too embarrassed to admit it, though. In fact, we

really shouldn't be because more and more experts believe talking to ourselves out loud is a healthy

habit.

     This "self-talk" helps us motivate ourselves, remember things, solve problems, and calm ourselves

down. Be aware, though, that as much as 77% of self-talk tends to be negative. So in order to stay

positive, we should only speak words of encouragement to ourselves. We should also be quick to give

ourselves a pat on the back. The next time you finish a project, do well in a test, or finally clean your

room, join me in saying "Good job!"

     Often, words come out of our mouths without us thinking about the effect they will have. But we

should be aware that our words cause certain responses in others. For example, when returning an item

to a store, we might use warm, friendly language during the exchange. And the clerk will probably

respond in a similar manner. Or harsh(刻薄的)and critical language will most likely cause the clerk to be

defensive.

     Words possess power because of their lasting effect. Many of us regret something we once said.

And we remember unkind words said to us! Before speaking, we should always ask ourselves: Is it

loving? Is it needed? If what we want to say doesn't pass this test, then it's better left unsaid.

     Words possess power: both positive and negative. Those around us receive encouragement when

we speak positively. We can offer hope, build self-esteem(自尊)and motivate others to do their best.

Negative words destroy all those things. Will we use our words to hurt or to heal? The choice is ours.
