Avoid Saying:
1. You can become the best.
2. You're definitely the best on the team.
3. This year, you have to play in the first team.
4. Today you were much better than Kostas.
5. I’ll talk to your coach.
Use Instead:
1. You can improve.
2. You’re one of the players who puts in the most effort.
3. This year, you have a great chance to improve your game.
4. Today, when you played with Kostas, you were very focused.
5. You can talk to your coach — and I can be there with you if you'd like.
