If I look back through my career, the best times have been when when I have been rewarded with an opportunity because of the work I have been doing. From grabbing these opportunities I have varied challenges and worked in many different countries and culture.
Science of the brain tells us that as human beings we seek out novelty. That means new ideas, activities, sights and sounds. Novelty is linked to learning and the learning that we achieve can be used to our advantage. There is a specific part of the brain linked to novelty which changes when something completely new is introduced to us. A chemical called 'dopamine' is released.
The reaction is not the same when something different but similar is introduced, it has to be completely different.
The chemical released is not a reward, it is a chemical that motivates us to look for something else novel as that 'new' experience can bring its own rewards.
If we use this knowledge with our individuals and teams then we can add novelty to our external list of tools. We can introduce new topics, tool-sets or approaches. New environments also work.
