Being clear is harder than being clever, and people remember clear.

Cleverness is available to anyone with a thesaurus and a bit of nerve, and it often exists to cover a thought that has not been fully worked out. Clarity requires understanding the thing well enough to say it simply, which is much more work. Readers register the difference even when they cannot name it.

Take something you wrote and remove the cleverest sentence in it. See whether the meaning survives, and whether it is now stronger. Aim for the version your reader could repeat to somebody else from memory, because that is the version that travels.
