What is the power-up of mind? I think it can be compared with the maintenance of a car; filling of high-octane gasoline, overhauling of engine or improving of engine itself. When we have in mind some delicious goal, like a horse with a carrot on its head, we must be cheered up. It's like a car filled up with high-octane gasoline. Also, like overhauling, refreshment makes mind be cleaned and produce balmy vitality in mind and body. But the effects is only temporary. The deeds have no other effects. On the contrary, if you change your viewpoint and reconst yourself from the origin, "what is human being?",you will obtain new power and then you are not what you are. You will be able to climb up the slope which you thought you couldn't climb up. And more, your speed and efficiency in work may come to be improved. When engine has enough power to move smoothly, the driving become more enjoyable. In the same way, in mind, obtaining strong power and smoothness enable your dream to expand. That not only broaden your view, but also you come to be able to find significant points. So you can see the important things which you have ever missed. I think human development start with it. Power-up of your mind can make not only you happy but also people around you happy. So power-up of your mind can change the pleasure of your life into the more worthy one. I think from the point the perspective of business get widened.
