Ideation readying

Sometimes we have a vague idea of what to do, but we don't feel quite ready or brave enough to take the idea to the next stage. We need a push, an intervention, a serendipitous stroke. It's a person or event that triggers our will to ideate that gives us a good excuse to go do what we know we should do. Do you have any first thoughts about how to put yourself on the ideation runway ready for takeoff?
