Worry

It's tough to be creative when you are filled with worry. If you are worrying about your grade on a project or how your boss is going to react to your ideas, you are going to have a difficult time getting into a creative mindset. You need to be able to completely free your mind in order to have the flexibility to go into unfamiliar territory and find innovative ideas. Here is one technique to reduce your worry about the outcome of a project.

Gather all the Facts
Without all the facts, there is no way to know how to move forward. Most worry occurs because you are uncertain about what direction to take on a particular task. The more facts you have, the more certain you will be. If you need to make a decision at the end of the week, don't even think about the decision until Friday. Spend the whole week objectively gathering all the information that you can about the decision. When Friday comes along, you will probably find that the facts have already made the decision for you.
