I've been waiting more than 30 years to say this: "Dad, I always told you I'd come back and get my degree." I want to thank Harvard for this timely honor. I'll be changing my job next year…and it will be nice to finally have a college degree on my resume.

释义：解决困难问题，应从还比较易于处理的时候开始；铲除邪恶，应趁它尚在细微的时候进行。
