This quote used to be my life motto. My "mission statement", if you will.
The turning point in my life, however, was the day I realized I can't change the situations and people in my life, and instead of feeling like a failure, I walked away feeling more hopeful about them than I ever had before.
Because I'm not the change that the world needs, Jesus is.
God can do so much more than I ever can, my only regret is that I'm just now learning to entrust to Him the things I can't control.
So now i look at what I can't change, and I see hope, not despair. I am not overwhelmed by the problems that surround me, because I know what the solution is, and it's not me.
