I'm Always Chasing Rainbows

At the end of the rainbow there's happiness
And to find it how often I've tried
But my life is a race
Just a wild goose chase
And my dreams have all been denied
Why have I always been a failure
What can the reason be
I wonder if the world's to blame
I wonder if it could be me
I'm always chasing rainbows, watching clouds drifting by
My schemes are just like all my dreams
Ending in the sky
Some fellows look and find the sunshine
I always look and find the rain
And some fellows make a winning sometime
And I never even make a gain
I'm always chasing rainbows waiting to find the little bluebird in vain
