You will have more effective ways of dealing with problems, better thinking strategies. Not only will you solve problems, but you will also be able to change the thinking that led to the problem in the first place. Your 'trying harder' days will be over, or at least severely curtailed. Problem solving is often like pushing on a 'stuck' door to open it, only to find that the door opens towards you. Systems thinking is finding out which side the hinges are on and in which direction the door opens.
Systems thinking is a basis for clear thought and communication, a way of seeing more and further.
Obvious explanations and majority views are not always right. With a wider and different perspective, you can see exactly what is happening and then take actions that you know are best in the long run. Systems thinking will help you to go beyond blaming others or yourself. Most blame is misdirected, for people are usually doing the best they can in the system they are in. It is the structure of the system, not the effort of the people in it, that determines the outcome.
