Well, if you need an answer, you need to ask yourself this question ? What is it that you want to achieve in the long term? Do you want to run a business that employs 100's of people and generates a ton of revenue? Or do you want to run a business that is location independent, employs a few people and you can make a small side income.
In either case, I feel that building a personal brand does go a long way in achieving your goals.
