Do something that's never been done

Well ..............
It's easy to narrate or express, but definitely isn't easy to do or to say ..........

trust me! 'coz if that's easy, it may have been done (or said) long before!

Sometimes, there is (most likely) a thing that you wanna do, but never been done; or a thing that you wanna say, but never been said. Though you have been pondered the thing many times, and came up into final decision to do (say), or forget it forever. Yet, I am pretty sure that the mission won't ever been accomplished, though the time has come or even have been passing.

It's easier for Chris Martin to sing and suggest it ....... but let people make their own decision.

Are you lost or incomplete?

Do you feel like a puzzle, you can't find your missing piece?

Tell me how you feel
Well I feel like they're talking in a language I don't speak
And they're talking it to me

So you take a picture of something you see
In the future where will I be?
You could climb a ladder up to the sun
Or write a song nobody had sung
Or do something that's never been done
Do something that's never been done

So you don't know where you're going and you wanna talk
And you feel like you're going where you've been before
You'll tell anyone who'll listen but you feel ignored
Nothing's really making any sense at all
Let's talk, let's talk
Let's talk, let's talk

and until the end of this song, (I do believe) that you won't ever talk about it, 

whatever it is! 

then keep it as it is.
