The first half of a year as a postdoc was full of surprises. I was surprised that switching topics is so easily possible within academia, and that apparently, people had enough trust to offer me this position (or they didn't care too much).
And of course, there was and still is the constant excitement about the new field, the new techniques, and the new people around me. Switching topics was a gut decision, and to be honest, during the first months, I had ever-growing doubts if this was the right decision. Now, I know (at least I think I know) that it was the right decision. In a more and more specified academic system, I think it is necessary to also broaden and not only deepen your knowledge and expertise.
