Classic Poem

Art going to do a kindly deed?
'Tis never too soon to begin;
Make haste, make haste, for the moments speed,
The world, my dear one, has pressing need
Of your tender thought and kindly deed.
'Tis never too soon to begin.

But if the deed be a selfish one,
'Tis ever too soon to begin;
If some heart will be sorer when all is done,
Put it off! put it off from sun to sun,
Remembering always, my own dear one,
'Tis ever too soon to begin.
