There are worse faults a person could have, but this one tends to cut into productivity so I've made attempts to overcome it. I find the best weapon is embarrassment. Self-induced embarrassment, that is.
Case in point-I have great ambitions when it comes to keeping fit, but usually decide that the best starting date is "tomorrow' whenever that might come. The solution? I've signed up for a 20k half marathon this fall in Vancouver, part of the Rock 'N' Roll Series, and the only one in Canada. Having made my declaration publicly, I now have no option but to force myself into a training regime. The alternative is embarrassment and admission of failure. I've decided the training will be less painful. I'm starting slowly, at 3 or 4 ks a day, because I'm terribly out of shape and not a youngster anymore, but then I have six months to hit the magic 20 k within a four hour limit.
I use this in other facets of my life as well. I never had the nerve to send my first short story to a magazine until I announced my plan to friends over coffee. The same scenario unfolded when I decided to send my first romance novella to a publisher.
Embarrassment, or the fear of embarrassment must be one of the world's greatest motivators, or is it only me?
