Most often we point out our anger towards people rather than focusing on the real problems, thus complicating the situation further.
Being the controller of our own life, we can choose where to put the focus. Our focus should be on the problems, not on the people. It should be directed on the solutions, not finding excuses.
Focus, when directed on right thing lets you have the control over your life and resolve the problems. Also we can have a better understanding of the situation so that solutions can be easily found.
