Kaizen (Japanese for “improvement” or “change for the better”) refers to a philosophy or practices that focus upon continuous improvement of processes in manufacturing, engineering, supporting business processes, and management. It has been applied in healthcare, government, banking, and many other industries. When used in the business sense and applied to the workplace, kaizen refers to activities that continually improve all functions, and involves all employees from the CEO to the assembly line workers. It also applies to processes, such as purchasing and logistics, that cross organizational boundaries into the supply chain.[1] By improving standardized activities and processes, kaizen aims to eliminate waste (see lean manufacturing). Kaizen was first implemented in several Japanese businesses after the Second World War, influenced in part by American business and quality management teachers who visited the country. It has since spread throughout the world.[2]

I should look at that more often and find ways to understand and use the philosophy

When your sitting at the trainstation, waiting for your ride home and this wrecked, wine-drinking psycho next to you starts talking about his life and everything, you will be reminded that all those tie-wearing pseudo-individuals are nothing more than skin and routines. Sometimes you may even feel connected to this shithead. Not out of pity, but the energy he sends out. You will see that no one of the others around you is like this. They are not trying to connect, they are self-connected with their iPhone-earplugs.
You don’t have to be this way. Take your headphones, put them in your pocket and enjoy your surroundings. If you don’t like what you see, be aware that your ignorant behaviour made this happen in the first place.
