As I am going through a time of healing right now I have been focusing a lot on gratitude to help me. Here are some of the biggest things that it's done for me.
Space - "Gratitude turns what we have into enough"
Clarity - "The blessings shine when we count them"
Love - Recognizing those who have made sacrifices helps us love them more.
