Whether rich or poor, we all have problems: that unfaithful mate, that annoying colleague, that persistent(持久的) disease, and the investment that is turning into a huge loss.

How can we remain calm, positive and even elegant in the face of all these difficulties of

life?

The following suggestions may help.

It comes with the pay. I have a friend who used to complain about her dead-end job and

unreasonable boss. Sounds familiar? One day I told her, "Look at it this way. You are getting

paid for the annoyance as well as the work. It comes with the pay. "

This has become my favorite saying for work-related frustrations. "Take every day as a bo-

nus. " When we learn to treasure every moment of what we have, we begin to see life in a whole

new attitude.

It's all in the mind. Sure, the psychologists tell us it is important that we work at resol-

ving problems. But they also say if you try to resolve a problem that would not go away, it would

only compound(使更复杂) the frustration.

If you tell yourself there isn' t a problem, there won' t be one. It is all in the mind.

Stop thinking about your own problem-help others instead. A lady who is struggling a

life-threatening disease showed she coped with her illness by making herself useful, by offering

help to others in a similar situation.

She has spoken to at least five other women with breast cancer. She says that the sharing

has helped her to find fresh meaning in her own life.

Never give up on your dream. Why do we give in or give up when we meet difficulities?

ls it because we have no confidenee in our cause and no commitment (承担义务)for what we

pursue?

One strong-hearted lady was the late head of the tragic Kennedy family, Rose Kennedy.

She said this on nationwide television one week after losing yet another son to assassin's( 暗杀者) bullet--Boddy Kennedy:"And we go on our way with no regrets not looking backwards to

the past, but we shall carry on with courage. "

Not the end of the world. Do you know something else? I' ve learned that care as you

might, love as,you might, some people don't care back.

And it is not the end of the world. After all, it's not the event that makes a person, is it?

It's what we do about what happens to us.

It was said that Albert Einstein' s last request on his death bed was to be given his equa-

tions(方程式) and his unfinished statement. Einstein first picked up his equations and lament-

ed(悲叹) to his son, "if only I had more mathematics!" What a great persistent spirit!
