There's No Rewind Button.... So What Do I Sing?

rewind button

It's not what I say, it's how I say it

AND there's no rewind button, but others can replay forever!

My song should be worthy of replay, so let me listen to my thoughts for quality control. What am I singing?

Like eminent people who have their food checked before they eat it, I should check my thoughts - my intellect’s food - before putting them into practice!

If I’m sensible and knowledge-full I will first consider everything before I act.
