Is fear preventing you from taking action? Acknowledge the fear, watch it, take your attention into it, be fully present with it. Doing so cuts the link between the fear and your thinking. Don't let the fear rise up into your mind. Use the power of the Now. Fear cannot prevail against it.
So many people have this idea: I want to achieve something great or be somebody great. And they neglect the step that leads to greatness. They don't honor this step at this moment because they have this idea of some future moment where they are going to be great.
