"You are making the world a better place with every song you sing." - MDB (See previous post).
You do wish it would be that simple, or that magical. That you could make the world a better place, just by being creative - singing a song, writing a song, writing a play, performing in an art piece.
Or maybe just by being a positive person. You know, that "power of positive thinking" thing? What if by being a positive force, in your own life, and in the lives of those around you, you could be a force for change, for the good?
Not a super-hero. Just a "good" person. Kind. Considerate. Humble. With a smile on your face and a song in your heart.
You'd never be able to prove or document your positive influence. It's not a "scientific" thing that can be modeled or verified. So you just act "as if" it were true. You act as if your actions, your words, have some deeper meaning and power.
That's a thin reed. But you hold it. In your hand, in your mind.
