My mother had a friend who was an oil painter. She never finished a painting. She would work on it for weeks or months and bring it to the point that it only needed a few finishing touches - and then she stopped. My mother once asked her why she never finished them. Her answer?
"If anyone criticizes them, I can always say, I'm not done yet." By never completing the work she never put her own seal of approval on it. She never claimed it as "done". She never announced that she thought it was good enough. So she never had to face criticism or disagreement. The problem? She never faced compliments either. And she never owned it. By never stepping up and claiming it, she always cheated herself out of taking full credit for it. She also communicated to others (and to herself) that her own work was never quite good enough. And people will accept your assessment of yourself. Research has shown if you present yourself or your work with confidence, people will believe that you are competent. Likewise, if you present yourself or your work with apologies, people will accept your belief that you are incompetent. My mother's friend, by always saying, "It's not done yet" presented herself as incompetent of completing a work, as being unable to claim a painting proudly as being "good enough". So no one else did either.
I've seen the same with remodeling a house. The remodeling is never complete. The home owner never steps up the line and says, "This is how I want my house to look and I think this looks good". She avoids criticism or disagreement this way, but she never gets credit for a job well done. Nor does she have a house she can live in and enjoy. Procrastination is a powerful mechanism for avoiding "failure". The problem is, in avoiding completion you are failing. But it is a failure you bring upon yourself and that may be easier to live with than criticism from others. If so, it is important to see why the opinions of others hold so much more weight than your own. Why do you trust the judgment of others about how your painting or your house should look more than you trust your own? And why does a negative opinion from others have so much power over you?
