Competition is great. You are entering a new place with other players. Some of them look better than you are. Some of them even started training way back than you ever heard the competition itself.
What should you do?
Focus only on your practice. Be a better version of yourself. Enjoy the competition. But never let the competition defines you.
You are on this journey and fell in love with the process. Be consistent and never fall into the “I am not good enough” trap. Keep pounding the stone.
