It's sure that if you want to improve your Personal Brand you have to focus on this: if you leverage Social Media and your other online platforms to show your audience what your values are, as a business person and as a human being, more people will connect to you. But, the question is, what are your values? how do you want to show yourself to your contacts?
Hello! It all depends on what business you are conducting or starting. If is something fitness related, then you'll probably want to show how fit and healthy you are. So, everything is relative here.
I think personal branding is going to be new market place , where people can brand their self, their work and skill to this digital world.
