Step one among the way to solve problems systematically is for people to approach the problem with calm, selfconfidence expectation that there is a logical, possible solution just waiting to be found to the challenge. This approach reduce the tension down and relaxes your nervous system also and open your supernatural creative mind to the difference possible way you can get possible solutions to solve the problem.
Also your assumption from the beginning should be that every single problem encloses within it have the seed of it own possible solution in it. That solution is the turn side of the problem. The solution is also lying there waiting for us to detect that and that now deals with human comprehension and abilities to turn things around.
Please be a solution oriented person than being problem oriented. This deal with thinking in term of the positive action you can probably take and what coupd be done immediately to achieved rather than looking for who is responsible or who to be blame for the incident. But when you are in the process of finding possible way and continuous thinking and talking in term of find lasting solutions to the problem , you will become more optimistic, realistic, creative and calm in your reaction towards the problem we are talking about and the response coming from you.
