He had just proved to himself that he did have idea power because the question itself was an idea. Every time we worry and make excuses, we show we have idea power and prove our imaginations are working. The problem is that when we worry and make excuses, we are letting our idea power work against us. Writing in a journal or making up a story about our situation can help harness our idea power and make it work for us instead of against us. That can help reduce stress.
Stress is an enemy of creativity.
It tends to shut down our idea power. When we reduce our stress, our creativity comes back. Another way to reduce stress and free your idea power to work better when you are searching for ideas is to give yourself permission to come up with bad ideas as well as good ones. We may need to go through 100 bad ideas before we come to a good one. Just write down every idea that comes to you, no matter how ridiculous it may seem.
