Beginnings and endings count more than middles.
Consider this sentence: "I have never felt more frustrated." The intensity of that statement can be heightened by moving one word to the beginning.
"Never have I felt more frustrated."
If you move two words forward in the following sentence, you sharpen your tone: "You have asked me twice now to respond to your requests on short notice."
Here there are two candidates for relocation, both of which convey annoyance: twice now and on short notice. The latter phrase, however, already occupies a position of natural stress at the end of the sentence, so try moving the other phrase forward.
"Twice now you have asked me to respond to your requests on short notice."
Can you hear the difference?
The same words presented in a different order deliver the message with more emphasis. Like word choice, word placement is a powerful tool. Use it to your advantage.
