After a hectic Monday a gentle reminder that we are only one. We can do so much and no more and we need to be at peace with that.
It isn't a failure to get to the end of the day and not have completed all the items on your To Do List. What counts is that you gave the day the best you could. You did what you could in the allotted hours. Whether it was work, kids, play or whatever else demanded your time and attention.
Go to bed at peace with having given the day the best you could.
