I learned about CC quite late, I played freeroll at WPT G. I started working and gradually leveled up in the rooms. I improved a lot after the training sessions here, learned how to collect information from the players I met and gained quite a lot of achievements. Collecting information and understanding the opponent's pulse are the skills I find most important when playing Poker to compete at the table (I can list them but I won't write them down).
Currently, I still regularly watch livestreams on social networks of clubs in the area where I live and have also achieved certain achievements.
Remember, To know oneself is true progress!
