- Learn one or two a day, not twelve. Pick your favourites from this list and use them today.
- Write your own sentence. Make it about your life: “I was over the moon when my cat came home.”
- Review them again in a few days. Your brain keeps words longer when you meet them again later. Here’s why spaced repetition works.
