How to write your own book, have you had any experience?

Before you go to the expense of publishing do get some honest opinions I have read some awful self published novels some I was unable to finish I know it wasn’t a cheap exercise I have read the occasional good one which I really enjoyed

Sit in front of your computer and write a set number of words every day no matter how poor you think they are.
After a week, read and revise all you have written.
You will begin to realise whether you need to plan, research or simply get it all down on paper.

Then start work.

Hello blue blossom. If you type Story Keeper into google, then go to it, Story Keeper is a guided way to write your life story. It interviews you, asking succinct questions, that wakes up your memory !! It is a bit like a ghost writer, you tell it everything, and it edits if necessary. You can take a year or so, or just a week! It receives your pictures or certificates etc, and records your voice for grandchildren to remember you.
Our son gifted it to us for about £100, but can be less, or more!
I’ve not started yet, but it looks incredible.

Are we talking about fiction or non-fiction here? I have written and self-published a local history book which has sold well and continues to sell. I thought about it for ages then decided to just do it. I decided to give myself a year, otherwise it.might have gone on for ever. Do your research thoroughly and decide on your intended market first then just get writing. You can work out chapters as you go and decide whether to investigate publishers or self-publishing as you progress but it's important to.just get into the discipline of writing whether longhand or on your computer. I thoroughly enjoyed the research process. Keep all your paperwork organised. I have no experience of writing fiction but the process must be similar. Get those ideas down on paper first. I think the Writers Year book is very helpful and Writing magazine too. I haven't made a fortune but I have more than covered my costs. I feel it is one of the most enjoyable things I have ever done. Incidentally the title was one of the first things I thought of. Good luck.

Stop reading about it and just get writing. If you've not got anything written what have you got? Nothing.

Just start writing. See what emerges.
Or
You can plan it, chapter by chapter. Make a list of what you must cover.
Very exciting. Enjoy it.
