Twenty Questions lyrics

Is the cup half empty, or is the cup half full?
Does the sun rise at dawn, or does the earth just spin along?
Or is it all perspective on how we see the world?
How many countless life forms are on a little ball that twirls?

Are we intrinsically separate beings?
Or could we possibly be parts of the same thing?
Water feeds the plants and the sunshine makes them grow
So how can anyone be an island on their own?

Does life make me happy, or does it bring me down?
Do I have what I need, or do I just want what's around?
Am I seeing truth, or do I just see wool?
Well, is the cup half empty, or is the cup half full?
