In that case due to the dynamics and friction between humans, there is likely to be some people or actors that we can not manage so it will be a stumbling block that is difficult to shut down. If in our lives, we attack such people or actors (those who are difficult to build and for our purposes), keep in mind the "Connected" theory. This theory says that everyone is connected to one another. The person who is really difficult for us to control or influence it is connected with other people. Every actor in a network or ecosystem of human life are connected to each other. People as our stumbling block, we are connected with others who may be connected to us personally or others we do not know.
Thaks you....
