Your Book Isn't the Product
When is the last time you finished a business book and applied everything in it?
Most people never do.
It's human, I've read so many books and maybe applied one or two elements in some cases a few more.
But, it was helpful. The next thing I do if I haven't already is follow the author on YouTube or LinkedIn to keep them top of mind to reflect back to the solutions I need.
Your reader does not need to apply your book, they need to trust you enough to potentially hire you to help solve the problem.
