| I have been blessed with the opportunity in my life. It took the near-death experience of my dad to make me realize that my purpose in life is to 1 others. My dad suffered from leukemia (白血病) in 1998. 2 the pain and treatment that he endured inspired me to be a more kind and 3 person. I realized life is just too 4 and it was time for me to make some changes-do the things in life that I wanted to do without making 5 why I couldn't do them. My dad 6 a bone marrow transplant (骨髓移植) operation, and after that he was able to reuse his own "cleaned" marrow, so a donor (捐献者) was not needed. That was excellent 7 because donors who are a match are hard to come by. That 8 me to become a bone marrow donor and hopefully help someone else one day. I also 9 money for the cancer patients. Yet, I was not satisfied with just that. I had to do more, I 10 blood every other month and seek opportunities to do other acts of kindness daily. The opportunity, some days, presents itself very 11 and some days I have to seek it out. Either way, it comes. I would like to 12 one of my favorite quotes with you all. "In an average lifetime, a person 13 about sixty-five thousand miles. That's two and half times around the world I wonder 14 your steps will take you. I wonder how you'll use the rest of the 15 you're given." I want to use my miles to create foot prints of love in this world. | ||||
