I worked with a woman who shrieked at me because I wanted to write myriad colours.

"It's 'a myriad of colours'!" she yelled. "LOOK. In the dictionary. It can be a noun! It's acceptable to have the extra words!"

"Yes, but why use three when one is fine?" I asked.

Then I backed away slowly as she turned purple, and decided I would never care deeply enough to give myself an aneurysm. I comfort myself with the fact that I look very young for my age and have regular sex.
