Recently I had the privilege of joining ex German Chancellor, Angela Merkel on a panel. I have long been in awe of her leadership, not least for her endurance. She was in power for 16 years. I once asked her how she managed it, her response was "things have changed a lot."

I’m envious of people who don’t need that. There are people that just wander round the world and ideas fall down from wherever, and they sit and they strum a guitar one day and they write a song, and then they carry on living. I could never work in that way.

I would always be tempted to take a movie I liked less if the payday was twice as much, and I’ve interviewed a couple people that grew up with wealth and I’ve watched them navigate their career and I’ve been envious of it. Nick Kroll comes to mind. He has so much creative integrity. He just does what fascinates him.

I felt at the time that Eric was much more successful than I, he was extremely productive during his time in Zurich, and worked on many very original projects, germ line, cell lineage, sex determination, where not many people could follow him. I also had the impression that I was dependent on him because he had more fly experience and without him I would not have gotten the job. This made our start in Heidelberg a little difficult, until we sorted things out, and from then on we thoroughly enjoyed working in the same lab.
