What words bring to mind...

Smashing Pumpkins were a great reference point as an awnry teen and still as a more gentle adult. Some of their lyrics have a soundness on such a basic level. I'm striving for this simplicity and honesty with words and their meanings on my latest print projects. 

I think Picasso's words ring most true when he said it took him a life time to draw like a child. 

Soundess: noun

1. a state or condition free from damage or decay.

2. the quality of being prudent and sensible.

3. the muscle tone of healthy tissue.
