Don’t be an idiot.
And while we’re at it, a personal brand is hugely overrated. It suggests that you can advance your career by creating a reputation.
But don’t fool yourself. A reputation, or personal brand, is something you don’t fully control.
A lot of people try to tell you that you have to “enhance” your brand. I’ve heard it since 2004 when I got my first sales job while I was in college. The advice was, “work on your personal brand, and you can make a promotion very quickly.”
