You don’t get to tell people what your personal brand is, anymore than Nordstrom or Coca-Cola get to tell people what their brand is. You get to act and people get to perceive. Their perception is your brand.
Your brand is how others perceive you, not how you perceive yourself. While you get to influence your brand, you don’t control it because you can only influence, never control, others’ perceptions.
Preaching and talking mean but very little unless our lives are lived in perfect harmony with our teachings.
