What is a world, my boy?

A little rain, a little sun,
A little shore where ripples run,
A little green upon the hill,
A little glade, a little rill,
A little day with skies above,
A little night where shadows move,
A little work for men to do,
A little play for such as you;
A passing night, a coming morn,
A coming love, a passing scorn;
A blackest cloud a little bit,
With silver on the rim of it;
A little trouble, lots of joy—
And there you have a world, my boy
