We're all faced with difficult problems on a regular basis. In fact, sometimes you might feel like you'll be crushed by the weight of your problems. But how many of us use special creative problem solving techniques to tackle these problems? "I didn't know there were special techniques." you say. Believe it or not, many experts have given a lot of thought to the problem of problem solving.
The obvious first step to solving a problem is to churn out possible solutions, right? Well, some experts say that the first thing you should do is define the problem in detail, even if it seems obvious. Write the problem down on a piece of paper and start asking yourself questions about it: Why is this a problem for me? What is the source of the problem? What will happen if I don't solve the problem? What do I really want to accomplish? Keep asking questions.
Once you've asked these questions and answered them, potential solutions may turn up. Or u may not. If you're still stuck, some experts recommend going for a walk. That's right – you should simply walk away from the problem. A change of scenery can inspire new ideas, and not focusing on the problem can actually open your mind to new possibilities.
If you still come up empty-handed at this point, you might try an unusual technique that some experts recommend. Open a dictionary, or any book or magazine, and pick out the first word you see. Write down anything that word makes you think of. Then look at your problem again. Something that you've written down may change your viewpoints and help you see the problem in a different way.
