Write like a Writer.

A lot of our ideas never get tested in the real world by the people we want to reach because they're barely understood.
Most people hire writers because they want to stick a few lines or paragraphs alongside their products, tools and designs. Like a backdrop, you know?
There's a story about a scorpion drowning in water. A saint passing by chose to save it. He pulled it out of the water and the scorpion stung him, then fell back into the water. The saint took it out again. It stung him and fell again. The saint helped it out once more. A spectator was confused. He walked up to the saint and asked, "What's going on? Why are you helping it when it keeps—"The saint said, "Just like the scorpion refuses to change its nature, so do I.
Its nature is to sting. Mine is to save."

A roundabout way of saying just because a client only wants a few 'to the point' lines surrounding their product doesn't mean that's all you give them. (Besides, they have the 'I will never get tired of revisions' tool for that now, and for free.)
You show them what it means to write like a writer.
And they'll begin to see what you actually bring to the table.It's one thing to whine that clients don't appreciate our work, and another to do work that gets appreciated.
"Don't use words too big for the subject. Don't say 'infinitely' when you mean 'very'; otherwise you'll have no word left when you want to talk about something really infinite." - C.S. Lewis
