Is there a subject or hobby that you enjoy or know a lot about? If so, you can become an expert. Is there a subject that you would like to know more about? If so, you can become an expert.
First, make a list of ten or more subjects that you know a lot about or are interested in. Can't think of that many? Ask your relatives or friends to help. They may have more ideas about the things you are knowledgeable about than you do. Do they ask you questions and you give them advice? If so, you have knowledge about that subject.
Once you have your subject selected, do a little research to see if there is any interest in the subject. It is of little use to write an ebook on a subject when there is no demand or interest. Do a search on eBay, Google or any of the other search engines, or check Overture to see how many people are actually looking for information on the subject you selected. If there is an interest, proceed with your ebook. If not, pick another subject from your list.
Once you have concluded that there is an interest in your topic, that you are sincerely interested in the topic, and that you can provide honest and informative information that people want, you are almost ready to begin writing your ebook.
If you think you still do not have enough knowledge or want to learn more, you can do some research from books or by going online and using one of the search engines. Information is all around us. We just have to seek it out. You don't have to know every detail of a subject but should be knowledgeable enough to write a very informative ebook. As long as you are providing information that your readers want and need, you can become an expert.
Now, before you actually start writing your ebook, you need to determine who will be most interested in your topic. Is your targeted group going to be male or female? What approximate age group are they in? Is your topic geared toward a particular ethnic group?
Once you have determined who you are writing to and that they do indeed have an interest, you are then ready to start writing. Remember to keep it informative. Tell them something that they don't already know. Make it interesting. You don't want to lose their attention at this point, you want them to keep reading.
Don't stop just because you wrote one ebook. Continue with your research and write another ebook on the same subject. Since this information is going to be unique from the first ebook, you have now a second expert volume on your subject that you can earn additional money from.
If you don't like to write or feel that you just can't, you can always hire someone to write the ebook for you. There are several place online where you can hire a write. You could try elance.com, guru.com or rentacoder.com. There are more, just do a search on one of the search engines. You provide them with an outline and they will write the ebook for you. You then add your name as author.
Perhaps you have a friend or relative who is an expert on a subject. You can team up with them and do a "joint venture." They provide the information and write the ebook, or you can jointly write the ebook. You can then market the ebook and split the profits.
The hardest part of all of this is getting motivated to start writing. Once you start, you will be challenged to get it finished and start earning money from your ebook.
