Writing down what you're grateful for each day is extremely powerful. By changing our mindset to look at what's positive in our lives instead of what's negative we can completely change how we view life.
"Someday everything will make perfect sense. So for now, laugh at the confusion, smile through the tears, and keep reminding yourself that everything happens for a reason." Even if someday it doesn't make perfect sense, it happened for a reason.
I think one of my favorite feelings is laughing with someone and realizing half way through how much you enjoy them and their existence. I always, always get this feeling with my kids! Aaron and Michelle and Jordan!
