We all have a talent and we all are passionate about something, even if we don't know it yet. Passion can move mountains, especially when it becomes contagious.
I'm using my passion to write a book, and proceeds of that book will go to a cause that I am passionate about - helping to care for homeless children (1.6 million children a year are homeless - according to http://www.familyhomelessness.org/children.php?p=ts).
The last book I wrote has proceeds going to HALO Animal Shelter.
This is important because anyone can do something if they really want to change the world. I'm just one person, one self-published author. But with a little luck, and all my hope and hard work, I'm using what I love to power something that I will always believe in.
