Do as I say, not as I've done. I've been a published author for 10 years now and my author brand is all over the place because I didn't do the branding work upfront. I was not clear. I was not strategic. I just followed the whims of my heart and the content in my hard drive.
That's not the way to do it. I've learned my lesson and now I'm busy cleaning up the mess.
I don't want that for you. Get clear on your brand direction first. Stick with it for a couple of years. You can always pivot later.
Your brand isn't written in stone. But if you aren't clear and purposeful with each book you write, you'll end up like me with an online footprint that's a mess and that often attracts the wrong opportunities your way.
