A brand is not a product or a promise or a feeling. It's the sum of all the experiences you have with a company.
Your brand is a combination of your reputation, your identity, and your promise. It's what you say, what you do, and what others say about you.
Your brand is what people say about you when you're not in the room, and what they say is based on what you do, not what you say.
Brand yourself for the career you want, not the job you have.
A brand is worthless if it doesn't connect with the right audiences in a relevant way.
