Something doesn't just add up.
And this is barely a puzzle.
How can everything be so important?
Each line must provide a clue.
Maybe there's an alternate way to find the answer...
To what this OP is craving.
The sum of the parts is equal to the whole.
Something does actually add up. But if at first you don't succeed, try again.
There happens to be an entirely different and unrelated answer from what I had in mind that I will accept as well. By happenstance I stumbled upon it and it nearly fits perfectly.
