"Consistency, clarity, and authenticity are the holy trinity of a great brand."
Quote from the book: Make a Name for Yourself by Robin Fisher Roffer.
Brand consistency can only follow by brand loyalty. When developing your brand, study it's most important qualities, key attributes and define it's characteristics.
Be authentic. Dig deep into who you are and what you believe in. Your brand must reflect your authentic self. Focus on what is unique about your brand, don't try to be identical to another brand. This is what will set your brand apart, thus building confidence.
There is only one YOU in the world, why not make your brand the same? You can make this happen because you are the ONLY one that can pull it off!
