You live your truth. You live your heart. Without fear. Because when it comes down to it, each of us in this life has to be our own hero. For some of us that was modeled, for most of us it is not and when it is I'm not sure how realistically it is modeled (thinking TV and comics). Don't get me wrong. I'd love to be Jessica Jones. Except she's absolutely miserable, alone and bitter. And her being beautiful and powerful doesn't make up for that. That her interactions are 100 times more intense than anything we do in our daily lives doesn't make up for the fact that it's never silly, funny and frivolous which life at its core truly is (just a crude example).
Point is. To be the best version of you, the one you see glimmers of when you look in the mirror, you have to live the example. And it's not hard to do, not for a second. It's easy as pie when you lead your life with your heart first.
