There are lots of people willing to give you advice on improving your business, and many of them have written a book (or two). “Getting Naked” by Patrick Lencioni is one of those books, but one I recommend reading.
It gives advice that is easy to understand and he presents it in the form of a fable. It’s quick reading but to really implement his advice will take time and practice. For more information you can check my article Getting Naked.
One piece of advice, don’t google the title, instead search for the author or visit his website.
