When all else fails in your day, you can fall back on this: 

Life is lived 24 hours at a time. 

You can’t control tomorrow, you can’t change yesterday. 

All you have is here and now. 

Biblically, you might say it this way, “His mercies are new every morning.” (Lamentations Ch. 3)

Some days, you just have to “call it,” and say, “I’m not sure I can do any better today…” 

(Making sure to ask forgiveness where necessary…)

“…But I can just close the door on today, trusting that tomorrow will come and I will have another chance to do/be better.” 

When all else fails, you still have another chance tomorrow. 

This is a way to keep moving forward and not get stuck in today’s failures (or successes for that matter.)
