If you love to write and you've been writing for some time and your articles have been on self help, you might want to consider looking over those articles and see where most of your knowledge lies. If you see that there is something there that you know a lot about first hand and have found that it has helped you, you should consider taking that knowledge and try writing a self help book. This way you can share with others what has worked for you and share how they can learn to benefit from the same advice.
You need to start off by defining your goal. You need to have a message and a purpose before you even begin. You should be able to say why it is you are writing the book in just a couple of sentences. If you can't do this and you can't narrow down your topic then you're probably not quite ready to put your book together yet.
If you have a goal then you are set and you need to make sure that the topic you have chosen is one that you know pretty good. You need to be really familiar with the different concepts of the topic or actually know from first hand experience about the topic. The more you have actually experienced the topic the better your advice is going to sound and the more believable it is going to be. Readers what to be able to feel like they can trust what you are saying.
You also need to make sure that you are inspirational. You need to make sure that your book gives off a positive mood. You want to be able to help the reader to want to change by motivating them. You should have a tone that will encourage your reader to follow your advice. You should include real life success stories or even anecdotes that will back up the advice you are trying to give. The story or stories will help your readers to visualize it.
You can outline your topic plan by setting it up in your table of contents. When a reader looks at the table of contents they should get an immediate sense of what the entire book is going to be about. This will help them decide immediately if they want to read the book or not, so make sure the table contents is put together well.
If you have sub-topics within your topic then you need to make sure that you use just one of these per chapter of the book. You want to make sure that the book stays clear and you don't make it confusing to the reader by mixing up all of the different ideas together in one chapter. You need to lead your readers from one the point they are at to the next step and continue you to lead them step by step through each individual chapter.
You need to be able to validate what you are suggesting to them. You need to be able to give them some sort of proof that the advice you are giving really does work. You need to use true life examples as well as data to back up your claims. You should try to include yourself as an example letting them know that if it works for you it can also work for other people.
You will need to also make sure that your book includes different kinds of resources like support groups and websites that can be helpful to the reader if they want to learn more or get more involved in whatever it is your topic covers. This way you are giving your readers the opportunity to connect with others who understand the topic you are writing about as well.
Before you go and try to publish your book whether it is in eBook form or printed form, make sure that the language you have used in the book is in plain everyday language that others can easily understand and that it comes off inspiring. You should also consider letting a few people you know read it so that they can give you their feedback as well.
