One of the biggest mistakes I see coaches, speakers, and experts who write a book make is that they did very little to build their platform.
A platform is the foundation upon which you build your career. Very similar to a political platform, your author platform uses your message as the base upon which everything else in your business is built upon.
I was invited to do a Twitter Chat all about creating your own platform hosted by Sharvette Mitchell of Mitchell Productions, LLC. Sharvette is excellent at doing web and graphic design. You can check out the recap here.
