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.
Make sure you aren't more invested in their recovery than they are. You can't do it for them, it's their path.
