Today’s first glitch:
Change the comma after age to a period.
Delete the comma after is known and capitalize She before it.
This young girl is very powerful for her age. She can heal people and predict the future. She is known far and wide. Even the rich and powerful travel across the world for a few moments of her time.
Powerful seems to mean different things in different sentences here; in the first sentence, it refers to the girl’s “powers” (healing and predicting the future), whereas in the second sentence, it seems to mean important/influential. Consider replacing the first powerful with something else.
