From a friend of mine.

A wise and witty friend sent me this quotation from a fella called
Stephin Tobin. Makes sense to me.

"Business people are like bricks.

Creative people are like wine glasses.

When the brick and the wine glass collide, the brick always wins.
But remember this; you can’t drink wine out of a brick."

Billy Wilder had something like this as well.
He defined an associate producer as the only person
who would associate with a producer.

(He was talking about movie producers, who are often money men.
Not agency ones, who are often creative.)
