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 of my dreams
Ending in the sky

Some fellows look and find the sunshine
I always look and find the rain
Some fellows make a winning sometime
I never even make a gain
