Life comes in a package. This package includes happiness and sorr ow, failure and success, hope and despair. Life is a learning proces s. Experiences in life teach us new lessons and make us a better p erson. With each passing day we learn to handle various situations. Love Love plays a pivotal role on out life. Love makes you feel wanted. Witho ut love a person could go hayward and also bec ome cruel and ferocious. In the early stage of our life, our parents are the ones who shower us with unconditional love and care, they teach us about what is right and wrong, good and bad. But we always tend to take this for granted. It is only after marriage and having kids that a person understands and beco mes sensitive to others feelings. Kids make a person responsible and m ature and help us to understand life better. Happiness and Sorrow Materialistic happiness is short-lived, but happiness achieved by bringing a smile on others face gives a certain level of fulfillment. Peace of mind is the main link to happiness. No mind is happy without peace. We rea lize the true worth of happiness when we are in sorrow. Sorrow is basic ally due to death of a loved one, failure and despair. But these things a re temporary and pass away. Failure and Success Failure is the path to success. It helps us to touch the sky, teaches us to survive and shows us a specific way. Success brings in money, fame, pride and self-respect. Here it becomes very important to keep our hea d on out shoulder. The only way to show our gratitude to God for besto wing success on us is by being humble, modest, courteous and respectf ul to the less fortunate ones. Hope and Despair Hope is what keeps life going. Parents always hope their children will do well. Hope makes us dream. Hope builds in patience. Life teaches us n ot to despair even in the darkest hour, because after every night there i s a day. Nothing remains the same we have only one choice keep movi ng on in life and be hopeful. Life teaches us not to regret over yesterday, for it has passed and is be yond our control. Tomorrow is unknown, for it could either be bright or d ull. So the only alternative is work hard today, so that we will enjoy a b etter tomorrow.

My name is Daphne Fu, and I'm the Project Manager in Taipei for Jackson&Wang. I'm here today to present our firm's marketing plan, which is designed to introduce EarthSound's products to the wealthy Taiwan market. Our research shows that there are big profits waiting in Taiwan, so we're excited at the opportunities we see for EarthSound. I hope that some of our excitement will rub off on all of you. 下午好，感谢各位今天的莅临，我是Daphne傅，Jackson&Wang公司台北地区的项目经理。今天在这里向各位说明本公司的行销企划，是针对贵公司将产品打入富裕的台湾市场所拟定的。根据我们的调查，台湾市场潜藏着丰厚的利润，对于"天籁"所面对的机会，我们感到十分兴奋，希望能把这种感觉传达给在座的各位。 I'll start with a few facts and figures about the health and beauty products market in Taiwan.
