Up and Down - Which is Better?

Up and down, up and down,
That's how our life is,
Up and down, up and down,
We will live all our lives like this.

Up and down, up and down,
All prefer the up than the down,
Up and down, up and down,
Most are living the down.

Up and down, up and down,
Which one is better?
Up and down, up and down,
The up keeps us happier.

Up and down, up and down,
Without the down, we'll never learn,
Up and down, up and down,
Which is your choice - ermm...?

The thorny road to the light,
Or to forever walk the straight line?
