Analysis of At Set of Sun

If we sit down at set of sun,
And count the things that we have done,
And counting, find
One self-denying act, one word
That eased the heart of him who heard,
One glance, most kind,
That fell like sunshine where it went--
Then we may count that day well spent.

Or, on the other hand, if we,
In looking through the day, can see
A place or spot
Where we an unkind act put down,
Or where we smiled when wont to frown,
Or crushed some thought
That cumbered the heart--ground where it stood--
Then we may count that day as good.

But if, through all the life-long day,
We've eased no heart by yea or nay;
If through it all
We've done no thing that we can trace,
That brought the sunshine to a face--
No act most small
That helped some soul, and nothing cost--
Then count that day as worse than lost.
