Future Perfect Progressive

"There's things I want,

There's things I think I want,

There's things I have,

There's things I wanna have,

Do I want the dreams?

The ones were forced to see?"

This is the first part of a wonderful English song--"Just Looking" by Stereophonics

Every time I listen to it, I always ask myself if I know what it means really.

The answer usually is definitive.

I know the words and sentences are sample and easy to understand, still I believe it has deeper sense that is worthy to think.

"They say the more you fly,
The more you risk your life……"

Is this true?

What does it mean “the more you fly, the more your life.”?

Should we take out our courage to chase after our dreams?

Even though the dream is a risk……

"I'm just looking,
I'm not buying,
I'm just looking,
Keeps me smiling."

You’re just looking?

Dose it mean you’re looking for something?

Buying what?

We cannot buy the feeling of happiness, it is nonsense, right?

I really have no idea what to buy……

This song is just like a meaning smile, I want to understand it real.
