No one else in this world has the incentive or urgency to manage your brand that you have- not parents, spouse, friends, or boss- only you. These important people in your life can support you as you build and maintain your brand, but they cannot do it for you as well as you can do it for yourself.
Managing your personal brand creates value for the people with whom you interact or serve. The personal benefit to you in terms of professional growth, income, and satisfaction are by-products of the value you add in others’ lives. So, far from being a venture in self-indulgence, personal branding is an ongoing process of creating benefit for the world around you.
