'Time' is the ever-elapsing moment of 'now'.
When you read 'now' just 'now', that moment elapsed, replaced by another 'now'.
'Now' is the only 'time' there is. Time isn't stored somewhere to revisit. So you have to live in the 'now' moment. That's the only 'place' 'where'...when...you can act on the world around you.
I just told a new member of John Lennon's lament about throwing away a lot of stuff he wrote as a young boy and man.
"Who was I to judge?" he asked.
Song-writers make judgment calls throughout the process, the elusive question of 'Enough', 'Not Enough', 'Too Much'.
How much Introductory Movement is Enough? In Synchronization Licensing I read somewhere that seven seconds is 'Enough', because the whole composition may only be fifteen seconds, thirty.
How much Lyrical Exposition, setting the scene, putting the 'properties' on the stage where the Singer-Character will act the story out?
How much Lyrical Exposition is 'Enough' before it is 'time' to get to the point, the gist of the song, THE Hook, the title line?
How should the melody go, up or down in pitch, sustained notes or short notes?
Judgment calls, the writer's privilege and responsibility...'response ability'. Only the song-writer can make those decisions.
You have much at your disposal to keep doing what is possibly one of the main things you came here to do. Keep doing it.
I can't think of a better way to 'invest' your time.

There will always be another song to be written. Someone will write it. Why not you? www.garyeandrews.com
