'Tomorrow never comes'
Literally and metaphorically. Both!

Literally, well, we all know tomorrows turn into todays.

Metaphorically, its a never ending game.
It's an El Dorado, an unchievable desire.
A vicious circle, we are trying to catch hold of,
yet getting trapped in its endless orbits.

Meaning, if you have a plan, execute it Today!
