It begins with you - take an honest look at your thoughts and behaviors, and take responsibility for creating the life and the world that you want.
Whatever you feel is lacking in your life - peace, love, money, compassion, friendship, acceptance - give it to someone else and watch it flow into your life in abundance.
Many of life's most important lessons come from those people that force us to grow.
Be open to learning.

We live in a limitless universe, someone else's good fortune does not take away from yours. Use the success of another to up your game and help you to grow.
