Passion not Willpower

I recently had my 1 year anniversary living a vegan lifestyle.  Some non vegans wonder how I have so much "willpower".  I don't have will power, I have a true passion for animal rights.  Once I found out what happens, there is no way I could contribute to that.  That is what drives me.  And now I will never go back.  I recently saw a t shirt that says "never trust an ex vegan" I love that quote because once someone is a vegan and knows better and then goes back to not caring, it makes you question their character.  Just something to think about.
