Picture showing the concept of Flow  
When my children joined the Montessori-Kindergarden and then the Montessori-School I was told about an interesting concept: "The concept of flow". A detailed description can be found in i.e. Wikipedia. Since then I'm orienting my work in correspondence to this concept in my personal and professional life. I'm trying to move my work into the Flow corner piece. That is to get and maintain a high skill level and master with that set big challanges. Also I'm applying the concept to the group of my co-workers to work as a team so that each individual can reach the Flow corner piece.
