Have you ever promised to do something and then gave it your absolute all?
Here is a small story. Mia joined the school drama club. She showed up to every practice. She learned every line. She stayed late to help others. Her teacher said, “Mia, your commitment to this club is truly amazing.” But when Mia wrote about it in her journal, she used the word “commitment” in every single sentence. It started to feel repetitive and dull.
