7 reasons why writing a book is good for business:

Your book becomes a platform to showcase what you’re about, what you’ve learnt, what you have to share with others that can help them, why you do what you do and the contribution you want to make out in the world. It’s not just a business tool. The thoughts and ideas you share here are part of your core teachings, message, part of why you do what you do.
Yes. All that in just one book.
It’s a tool you can use to advertise your services forever more.
It’s a fantastic (if done correctly, massive) list builder – and has you noticed by other experts in your field.
You become an instant expert. You’ve actually taken the time to write a (- useful, beneficial) book.
It’s a visibility tool (think J.K.Rowling).
It’s an additional source of income (you still need to market it, it won’t sell itself).
It’s a basis for any number of e-courses and programs you want to create around your core message.

When should you write a book?

There are two main ways to go about this:

When you’ve got a fabulous life story and experience to share even if you’re just starting out in your business
It pays to wait until you’ve worked with clients for a while so that you’ve fully integrated the experience and lessons – you know what works, what doesn’t, you’ve tried a ton of stuff and know, truly know and live your message as well as being crystal clear on what your ideal client is after. Don’t just shoot in the dark. It’s a great list and profile builder but you must have the basics in place first. This also gives you greater authority in your field. Once you have a solid business message, now’s your time to write that best seller where you can package your most useful ideas and make a greater impact. This is how worthwhile ideas spread, by sharing your contribution to the movement you are a part of. And, see point below…

Write your outline/chapter list then start gathering what you’ve already written from free reports, blog posts and any other content where you share your message. This is another reason you want to wait until your business is somewhat established as you’ll have a ton of valuable material ready to use
If you’re a slow writer or you don’t like writing, dictate it then have someone transcribe it for you
My favourite tip: Book a long weekend writing retreat and basically get the entire outline of your book copy cut and pasted from existing sources, intro and conclusion written along with any additional material you want to include. It can be done and still give you time off for the beach or country walks in the afternoons if you focus during your morning and evening writing sessions.
