24. Lessons I learned from working with Ted: Enjoy what you do. Pay attention to details. “Published means forever” - write well! Prepare your talks. Pay attention at conferences. Read. You can be successful in science, AND a good person.

26. Your students, and your students’ students, and their students… We will always remember you, Ted.
