Reflection is a good thing. If I never stopped to reflect, I would forget lessons learned, prayers heard, goals earned. I find it incredibly helpful to take time to reflect at least once a week in order to keep my life focused on the correct goals, and aware of my past successes and failures. It can be too easy to lose sight of where I'm going, and where I've been.
Reflection always fills me with gratitude. I see all the ways, not always noticed at the time, that God worked in my life, His attention to details. That's priceless. Knowing and seeing how important I am to Him is an encouragement to keep the faith, to keep running this race that is set before me.
