I want a brighter word than bright - John Keats

Stop and consider! life is but a day;
A fragile dew-drop on its perilous way
From a tree's summit.

Sometimes goldfinches one by one will drop
From low hung branches; little space they stop;
But sip, and twitter, and their feathers sleek;
Then off at once, as in a wanton freak:
Or perhaps, to show their black, and golden wings
Pausing upon their yellow flutterings.

When I have fears that I may cease to be
Before my pen has glean’d my teeming brain,
Before high piled books, in charact’ry,
Hold like rich garners the full-ripen’d grain;
When I behold, upon the night’s starr’d face,
Huge cloudy symbols of a high romance,
And think that I may never live to trace
Their shadows, with the magic hand of chance;
And when I feel, fair creature of an hour!
That I shall never look upon thee more,
Never have relish in the faery power
Of unreflecting love! — then on the shore
Of the wide world I stand alone, and think
Till Love and Fame to nothingness do sink.
