I wandered lonely as a cloud --
That floats on high o'er vales and hills,
When all at once I saw a crowd,
A host, of golden daffodils;
Beside the lake, beneath the trees,
Fluttering and dancing in the breeze.

Continuous as the stars that shine 
And twinkle on the milky way,
They stretched in never-ending line
Along the margin of a bay:
Ten thousand saw I at a glance,
Tossing their heads in sprightly dance.

The waves beside them danced; but they
Out-did the sparkling waves in glee:
A poet could not but be gay,
In such a jocund company: 
I gazed --- and gazed ---but little thought
What wealth the show to me had brought:

For oft, when on my couch I lie 
In vacant or in pensive mood,
They flash upon that inward eye
Which is the bliss of solitude;
And then my heart with pleasure fills,
And dances with the daffodils.

This poem by Willliam Wordsworth, the earliest of the Romantics, tells us about the poet's love of nature and how it used to affect his innermost thoughts.
