"You have to explain to little children 'why' and you also have to listen to them and believe me, they will reason with you, they're unbelievable! So you can learn from everyone at any age. Life is about listening, leaning and never giving up. As long as you're here on earth, you're here for a purpose and it's not about you it's about what you can do to better the world you live in. And that's why I'm here, to help someone else up."
