In her autobiography, actress Joan Collins revealed that she ended her affair with Warren Beatty because of his annoying habit of accepting business calls in the midst of their lovemaking.

While you may not share Collins’ problem, interruptions can plague anyone who is trying to accomplish a dream. This seems to be especially true for those who are running a business from home.

Years ago, my mother called to ask me to run an errand for her and prefaced her request by saying, “Since you don’t work, dear….”

Your family and friends may think the same of you if you’re running a business from home. Such disruptions can not only impede progress, they can cause you to lose sight of your most important goals.

An interruption occurs when a lower priority intrudes on a higher one. We usually think of interruptions as being caused by another person who distracts us from what we are doing, but  we can also interrupt ourselves by letting petty things take up our time and attention.

Consider this confession from author Jessamyn West: “Whenever I’m writing a book I never get out of bed, because if I do get out of bed I always see something that needs dusting.”

The best way to handle interruptions is to prevent them before they happen and that requires taking a proactive stance. If you sense that distractions are sabotaging your efforts, keep track for a day or two of every interruption you encounter.

Is there a pattern? Are there people who keep showing up? What causes you to be distracted?

If people are causing the interruption, your first line of defense is to establish boundaries with those people who may have gotten used to your availability.

“No, I can’t run over and help you turn your mattress right now, but I will be glad to help you this evening,” is one way to handle requests that interfere with the project you need to complete.

The people who live under your roof also need to understand your need for uninterrupted time. One woman with teenaged children took to wearing a hat  when she was working to signal her family that she was to be left alone. Another gave her children permission to interrupt her only if someone was bleeding.

Don’t assume that other people will know that you don’t want interruptions. Tell them when it is and isn’t appropriate to contact you.

Whether it’s your family or friends, you’ll lower your frustration level considerably by explaining in advance that you are serious about your business and will be unavailable at certain times.

Preventing unnecessary interruptions falls under the general heading of Good Time Management. “Without the management of time,” said William Reiff, “you will soon have nothing left to manage.”

People who are highly productive tend to guard their time carefully. Your work matters, too, and deserves your full attention when you’re creating, inventing or planning.

Yet many people seem oblivious to the importance of limited accessibility and the mobile phone has made it possible to reach them anytime, anywhere.  Unless you deliver babies or repair computers, there’s probably no reason to be on call twenty-four hours a day.

Since the telephone is most frequently the instrument of interruption, it makes sense to be its master. Some people find it easiest to have a regular time to receive and return calls. Your answering message could even explain to callers that you will get back to them between 2 and 4 , or whatever fits your schedule.

Keep looking for creative ways to limit interruptions. Consider a quiet location other than your office for doing some of your work, for instance.

“Things that matter most,” said Goethe, “must never be at the mercy of things that matter least.”

Start every day with a brief review of what you want to accomplish and determine what has the highest priority.

Knowing what matters most is what makes it possible to finish that novel while the dust piles up—or to give your partner your undivided attention because you’ve finished your work for the day.
