I listened to a TED talk with Eve Ensler and I took down two quotes that resonated with me:
"When we give in the world what we want the most, we heal the broken part inside each of us."
"Happiness exists in action. It exists in telling the truth and saying what your truth is, and it exists in giving away what you wan the most."
So if you didn't have security growing up or an unstable family, you could now work in some capacity with children in need, or be a consistent presence to someone, and would probably feel highly rewarded and fulfilled. If you always felt criticized growing up, you can offer your friends a nonjudgemental ear and heal yourself by giving her that. These are clear ties, but there are so many blurry ways to heal our selves in service of others. And I believe there is a way to give that to yourself and your recipient in your work, your home or your community. Look for what you do that feels good, and it probably just smoothed out an old crack on your heart.
