What is the meaning of the poem below?
Yonder sees the morning blink:
The sun is up, and up must I,
To wash and dress and eat and drink
And look at things and talk and think
And work, and God knows why.
Oh often have I washed and dressed
And what's to show for all my pain?
Let me lie abed and rest:
Ten thousand times I've done my best
And all's to do again.
By A.E. Housman
