As a writer I spend enormous amounts of time chewing on pens, pacing floors and sitting frozen with my hands extended over the keyboard. Anyone who has written knows the paralysis before writing. You attempt to discern the perfect topic, the perfect tone, the perfect point of view and you become frozen. A long time ago I received the best advice; just start writing, it will come.

The key to any success, any endeavor is starting. I've long lost count of the individuals who tell me they have the great American novel, newest business idea, or are committing again to get in shape, and yet they haven't taken a step. Many of them won't. And it is not that they aren't committed or sincerely want to succeed. It just seems too overwhelming.
The other foe that has to be encountered is our inner negative voice. We come up with excuse after excuse, or very sincere, well-thought out reasons to avoid the challenge. Sometimes it is fear of success or failure, but mostly valid reasons keep us from pursuing our greatness today. Tomorrow after all is still a possibility in our reasoning.
The problem is that we allow these reasons and postponements to fool us into believing that eventually we will get around to our goal. I can't speak for you, but time seems to move rather quickly these days and all of a sudden I'm looking back at the end of another month, year or decade.
"Just do it" Nike proposes. There is sense in that axiom. When we jump in we find our equilibrium rather quickly. We realize that our task is not as difficult as we thought. There is also good research that early success (completing a small task or part of a project) will spur us on to continue.
So, jump in. If your fingers are poised over the keyboard, put them down and write. If you are waiting to start that business, write the plan. If you are getting in shape, walk to store to buy sneakers. But do something!! Because the worst regret in life is "I could have..."
