Never regret what made you smile. Just learn from the tears that followed.
Without darkness there is no light. (Bound to be a quote that I heard).
Life can be a difficult thing. Especially when you are young. There is a delicate balance in opening your heart too much or keeping it guarded and closed. We need people. But, in our humanity, we hurt others and others hurt us. The only way to become more is in relationship to others. It is the only way to grow our spirits. Just remember that after the storm, there comes the rainbow and then the sun.
