1. Apologizing after every miss. Hit another ball. 2. Trying to hit harder when you’re already missing. 3. Changing your technique because you missed three balls. 4. Saying “I know.” If you know, why are we here? 5. Going for a winner when you’re three meters behind the baseline. 6. Apologizing when you hit a great shot. Never apologize for greatness. 7. Blaming the racquet, strings, wind, sun… 8. Admiring your shot instead of recovering. 9. Complaining about the feed. Adjust your feet. 10. Saying “I usually play much better than this.” Of course you do. Everyone does. 😂 #tennis #slavic
