     Around twenty years ago I was-living in Seattle and going through hard times. could not find a satisfying job"and I found this especially difficult as I had a lot of experience and a Master's degree.

     To my shame I. was driving a school bus "to make ends meet (收支平衡) and living with friends. I had been through five interviews with a company and one day between bus runs they called to say I did not get

the job.

     Later that afternoon, while doing my rounds (当班出勤) through a quiet neighborhood I had an internal

(inside) wave-like a scream (尖叫) come upfrom deep inside me and I thought "Why has my life become so hard?"

     Immediately after tbis internal scream I pulled the bus over to drop off a little girl and as she passed she

handed me an earring saying I should keep it in case somebody looked for it. The earring was stamped with words' BE HAPPY'. At first I got angry. Then it hit me. I had been putting all of my energies into what was

wrong with my life rather than what was right! I decided then and there to make a list of 50 things I was

thankful to.

     At first/t was hard, and then it got easier. One day I decided to up it to 75. That night there was a phone call for me, asking if I would do a one-day training for 200hospital workers. I said yes and got the job.

     My day with the hospital workers went very well. I got a standing welcome and many more days of work.

     To this day I KNOW that it was because I changed my attitude' (态度) to gratitude.

     By chance, the day after I found the earring the girl asked me if anyone had looked for it. I told her no

and she snid"I guess it was meant for you then."

     I spent the next year doing training, workshops all around the Seattle area and then decided to risk

everything and go back to Scotland where I had lived Before. I closed my one man business and bought a

plane ticket. One month later I met-my wonderful English wife and best friend of 15 years now. We live in

a small heautiful house in Scotland.

     'THE ONLY ATTITUDE IS GRATITUDE' has been my motto (座右铭) for years now and yes, it

completely changed my life.
