My signature on the wall of the Sweat Room on the Rapenburg! Graduating in Leiden means signing your name in the Sweat Room. I wanted to sign near Princess Beatrix, so I would always be able to find my name. As captain at the helm of my studies, with the university's motto in mind: Praesidium Libertatis, the defence of freedom, I charted my course and achieved my goal. A wonderful memory.
