People who have addiction problems with drugs or alcohol have a much greater chance of success in beating the habit when they recognize, admit, and correct their self-defeating behavior. In the same way, entrepreneurs will excel when they learn how to get out of their own way.

You can’t move forward or achieve your goals if you become sidetracked by self-defeating behavior. You also lose your competitive edge if you’re always meeting your challenges in a self-defeating fashion, while your competition confronts and masters stressful situations head-on.

By definition, any repetitive behaviors that block your efforts to accomplish your long-term objectives are self-defeating.

Here are some common behaviors that may not be as self-destructive as an addiction, but are every bit as self-defeating if you don’t overcome them:

– Procrastinating. A perfectionist graphic designer kept turning his work in late, not appreciating that his timeliness was every bit as important as the quality of his work product. In a small business, people rarely work in a vacuum. One person’s work sometimes cannot begin until someone else gets his or her job done first. If you’re always late completing things, people stop relying on you, start resenting you and begin to bypass you.

– Not preparing well enough. The belief that what you want to sell is what people want to buy is a sure road to disaster unless you’ve thoroughly researched the market. A well-made buggy whip is a thing of beauty, and it sure is nice to hang in your den. Just don’t hang your hat on it, if your customers don’t share your love for a horse and carriage.

– Not following through. A manager of a moderately successful fitness club told me he no longer goes to seminars on management. He said the information at these seminars is always great, but implementing the suggestions and trying to convert his employees to the new approach seldom works. If something new is important enough to learn, it’s important enough to schedule company time devoted to the purpose of planning how to implement it.

– Not learning from your mistakes. Successful people don’t make fewer mistakes than unsuccessful people they repeat fewer mistakes. Truth be told, we learn more from our mistakes than our successes, and it’s a shame to miss out on this valuable education by not owning up to our errors. Unfortunately, you need to admit you have made a mistake before you can learn from it.

– Being competent, but less than charming. As people get older, they prefer to deal with capable but affable people, rather than brilliant but obnoxious people. One of the brightest management consultants I know was resentful that his poor interpersonal skills had cost him so much success. He kept ranting and raving, “Judge me by my results, not by my bedside manner. I’m not one of those brown-nosing game-players.” He missed the point that charm is more about putting people at ease than it is about being phony and obsequious. He also missed the boat when it came to the success his competence and talent truly did deserve.

– Saying yes when you want to say no. If you sacrifice respect in order to be liked by saying yes all the time, you won’t be respected or liked. It’s difficult to continue to like someone when you lose respect for him or her. At times, commanding respect starts with saying no to something that you disagree with, and then being flexible enough to work through the issue with the other person. I know a headhunter who routinely says no to prospective job applicants, because finding out how they respond to “no” reveals so much about their ability to cooperate and be a team player.

– Having unrealistic expectations. When you confuse what is reasonable with what is realistic, you set yourself up to fail. It’s reasonable to re-engineer your business; it’s unrealistic to do it all at once. A stationery supply store in Los Angeles decided to revamp its sales, operations and compensation policies (all of which were in need of modification) all at the same time. After six months, it filed for Chapter 11.

– Getting involved with the wrong people. A “nice guy” chief executive of a hardware chain hired a chief operating officer he thought was strong and tough. His grave error was to confuse stubbornness and rigidity for strength. By the time the timid CEO galvanized enough courage to remove the difficult COO, it had cost him several valued employees. Yes, there are bad people in the world. If you keep giving them the benefit of the doubt, you’ll be the one who has to clean up the mess.
