Why must I write using imagery?

Should I paint words as if those words
were canvases?
Should I paint words as if by coloring them,
I could draw the eye of the reader into my poems?
Should I just paint and paint words
for the sake of painting an image
into the reader's mind?
Should I?

Ah!

Should I just paint words for them to see
what reality does not allow them to see?
Should I paint words for them to feel,
what reality does not allow them to feel?

Or Should I just paint words and become an artist, and don't care about anything else, not about me holding a brush, not about me, having colors,
Just about me, painting what I see,
What I feel, while I paint words with whatever I have in my hands.

Should I?
