 I was lucky. I had a lot of places where I had leadership and friendships and work experiences. And I got this Ph.D. almost. It's a little crazy that I got it, I guess, when I think back at it. Did it help you? And it was very helpful because the thesis was very helpful. The thesis, when you're doing a thesis, there is no answer. And you go down all these blind alleys and you have to sort of conclude something from the data you've got.
