I got to be honest. I get frustrated sometimes, mostly with myself. Then this thought came to mind for me, "What if the lesson God is trying to get me to understand is that no matter how many times I feel frustrated with myself or everything breaks down, He gives me the courage to pick up and keep serving Him?" That would make this worth it.
Of course this could be all wishful thinking, and therefor moot. But either way I give my trust to God, and therefore it will be... all good.
