Here is a great passage from Martha Borst and her The Scoreboard in the Sky article...

What makes a difference?

Our thoughts, feelings, opinions, desires, fears - they are a part of our experience, but they don't make a difference in terms of results. They don't create a change. In the end, I will either have REASONS OR RESULTS. My results will tell me if my actions have been successful. My results tell me what I'm committed to…pursuing what I want or doing what's comfortable . . . producing the results or listening to the reasons.

Ultimately, the only thing that makes a difference is asking, "What's my next move? What's missing? What will it take?" And then . . . I must GO DO IT!
