Graphic Design, although occasionally rewarding, can be extremely labor-intensive and subjective. I have the gray hairs to confirm this fact.
Over the years, I have worked with a variety of clients, from WONDERFUL to CHALLENGING to ÜBER-CHALLENGING. There was one particular case, where I quickly boxed up a particularly over-subjective client's reference materials and sent them packing.
In certain situations, the immortal words of Chris Pinkham, a former member of the EYMER DESIGN TEAM, comes to mind.
"I love the clown but can we lose the makeup?"
Sigh. – Doug.
