„Matthew McConaughey's book 'Greenlights' is an very inspiring (and humorous) guide to life that has confirmed me in my own way. The core messages: don't hate, never say you can't do something, don't lie - and keep walking. Because even if you are standing at a red traffic light, the light will eventually turn green again. In the end life isn't about winning or losing, it's about accepting the challenge to just keep on living."
