Are you good at playing computer games? There's a guy whose name is Bert Ingley, from the United States. He loves playing computer games, especially sports games in the area of American football computer games. And he wrote a book on how to play sports games and he sell its on the Internet.
His website is called "maddentips.com". And he makes over $200,000 US a year selling his e-book on how to play that game.
Go to Google and type "lizard care book", or, "lizard care book". You will find a guy who sells books on how to take care of lizards and he makes hundreds of thousands of US on that.
There's also a whole series on how to take care of your dog, how to take care of your pet rabbit and many other different kinds of pets that you can think of.
Thus you can become an author just by writing about what you are good at
Here's another recommendation for you to obtain the ideas you need to become an author. Do you know that you can construct a book that doesn't have to be written just by you?
It could be a compilation of articles and nowadays you've got what we call public domain and its starting to get really, really popular.
A few examples I can give you is Peter Pan. You can publish a book on Peter Pan and not get sued because it's public domain. It's the same for "Dracula", and "Think and Grow Rich". All these and a few other famous titles are all listed under public domain
For those of you who are interested, you can go to Project Gutenberg. You can find it on Google, on a Google search or head down to "Gutenberg.org". What you will find is that any book that is published before 1923, you will be able to use it, modify it because there's no copyright ownership over that so it's an interesting thing.
In other words, you can write all those books and take all the content.
Here's a real life funny example. There's this lady, her name is Cindy
Cashman. You can visit her website at "CindyCashman.com". What happened to her was that she was dead broke and she came up with this idea of writing a book.
What did she do.? She wrote a blank book. And her book is called "Everything Men Know About Women". Now she has sold a million copies of that book. writing it under the pseudonym Dr Alan.
Through the examples and recommendations given above, you can now be sure that you will never run out of ideas or contents to write your very own book and becoming an author.
