I have learned throughout my life [so far] that friends come and go, there is betrayal between friends, etc.
God is constant. He won't betray me. When everyone walks out, He is the one that walks in. That is a great comfort to me.
That is my mission in life: to be transformed by God, not be conformed by the world. A characteristic of being transformed by God is letting Him take control and surrendering all to God. It's not always easy but the rewards are so much greater than the cost.
My one word for 2015 is focus. Daily [re]focusing on Him is worth every moment shared with Him.
