What Is The Source Poem by Mark Heathcote

What is the source of creativity?
Some would state it's their faith
Some would say it's their proclivity

It just naturally comes and conveys
These you might suggest are cliché
But we all have our own, protégé

And for that, we can be inherently
Thankful for all who came before us
With their inky pens or oily brush

What is the source of creativity?
If it's not, mush, what does it matter?
As long, as it's done & done, skillfully.
