More than likely, you have tremendous knowledge in your area of expertise. You can talk about different aspects of this until the cows come home. You want to share this knowledge with your potential customers. But you have one hurdle to overcome first. What's that? You haven't yet written your article.

Of course, there are no hard and fast solutions to this that will work for everyone. But here's a strategy that you might try. Start by clearing your desk and turning off your computer. (If you like to write on the computer, then close down email and any other distractions.) Unplug the phone and make sure that your family and friends will not disturb you or interrupt you for forty minutes. The problem with an interruption is that it can take twenty minutes to get back to where you were and you may not ever get back.

And it's not clever to multi-task. To have more than one job to do at a time is worse that being drunk, however important it makes you feel.

And here's the trick. Use a kitchen timer. If you haven't got one, buy one. Set the timer to forty minutes. No one can concentrate well for more than forty minutes. Now simply write about your subject without stopping until your subject is exhausted. You will be amazed at how many words you write. Don't stop, for any reason. Keep churning the words out. After all, this is an area that you know backwords. You don't need to think overmuch. Just put down the things you know about the subject. You want to engage your subconscious mind in this. Writing, like talking, should be easy and flow naturally from who you are and from your heart.

When you've finished a sentence, start another one. Keep moving forward. Keep confident. Know that you are imparting valuable information that will win you friends. Don't worry about spelling or sentence structure. This is your first draft. It doesn't matter if you make mistakes or decide not to use everything later on. The wish for perfection is usually the cause of writer's block. But writers know that your first effort is never perfect. But you have to start somewhere and you have to push on until there's nothing more to say on the subject.

When the kitchen timer rings, you are through. Put your effort  away and give yourself a treat. Writing for forty minutes will have exhausted you but you will also feel a terrific sense of achievement. Even if the only thing you do today is forty minutes of intense writing then your day will not have been wasted. After the exertion, relax totally. Play with your children, talk with your friends, make a cup of coffee. You need to relax completely, just as you need to concentrate completely whilst you are writing.

The next day, you can revisit what you have written and re-organize it. Or you can get a friend or colleague to do this for you straight away. Do not try to review your own work immediately. You will be too close to it and you will not be able to make sensible decisions about it. This is where you employ your conscious editing skills which are a world apart from your barely conscious mind that has created your first draft.

When I tell my friends that I write articles with my kitchen timer, they look at me as if I'm not the sharpest knife in the drawer but this works for me every time that I commit to it, and it will work for you too if you have confidence in your knowledge and abilities.
