Via the Tom Peters! blog, I was introduced to a great NXTBook (yeah, I had never heard of that either) by Rajesh Setty, Personal Branding for Technology Professionals. It’s a great resource for identifying and promoting your personal brand. Not a technology professional? No problem. There are some examples and points relating directly to the technology industry, but this document in no way is constrained to that field.
I recommend printing the document so you can fill out the simple exercises that help you develop your personal brand. I printed it out and even ran it through the binder, so it feels like a workbook and is something I can reference occasionally instead of losing it in a stack or throwing it away.
