The entities with which we spend most of our time lie in Macro environment. The place you live, the place you work, the colleagues, friends with whom you spend most of the time etc. All these are part of macro environment. Its very important that you put yourself in a macro environment which motivates you constantly to become successful. This also includes You, if you spend a lot of time with yourself(you are the environment in this case) and you have a reactive brain then most likely you will have reactive thoughts unless you change your environment.
