After Lies had twice given us a training on positive psychology, it soon went through the building: it was fantastic! Good content, she also drew a group with a difficult dynamic among themselves. I had never experienced this before: that more and more colleagues asked if they could also follow this training. The training eventually became the most popular training in the organization, which colleagues volunteered for in large numbers. Nice, because of course that is much better than when you send people to training. Even after the training Lies thought along in a very pleasant way about how we as an organization could move forward.
