New ideas and creativity tend to come when and where we least expect it. More often than not the ideas exist already just over the horizon or on the edge of our vision, waiting to be found.
Some people spend timing chasing ideas and others let them come their way. Our mind records thoughts and interactions and a flash of inspiration comes when connections are made between sometimes disparate ideas.
The challenge is figuring out what to do with that thought at that moment in time. I try to write ideas down immediately so that I can work with them later.
More important than a bright idea, however, is whether or not you are open to receive it.
