Everything flows well—until you realize you’ve used the word energy seven times in two paragraphs.
“The team showed great energy.”
“She walked in with positive energy.”
“The company needs more energy.”
“This drink gives you energy.”

You’ll learn:
- Which synonym fits physical strength vs emotional drive
