Tim Minchin --- comedian, writer, actor, musician and social critic --- received an honorary doctorate back in 2013 at his alma mater, the University of Western Australia, Perth. An abbreviated version of the address he delivered at the time, entitled "Nine Life Lessons," has been circulating again lately.
Minchin is funny, often profane and rarely a comfort to those who hold orthodox views on many subjects. His lessons, addressed to students, are worth listening to by folks of any age:
1. You don't have to have a dream.
2. Don't seek happiness.
3. Remember, it's all luck.
5. Be hard on your opinions.
6. Be a teacher.
7. Define yourself by what you love.
8. Respect people with less power than you.
9. Don't rush.
An edited, abbreviated and captioned YouTube version is here. If you'd rather watch the whole address or read a transcript of it, you can do that here, at Minchin's web site.
