Being a professional player is always difficult, let's consider different aspects, what can happen at a cerebral level to a professional player is the complete dedication to the game which causes the person to be constantly under challenge, this is not good for health and risks causing permanent damage to the person's character, then it also involves the emotional sphere, usually those who play always remain frozen, never an emotion
I wonder, excuse me if I'm pedantic and a pain in the ass, but how can you become a professional player when what helps you in the game is also luck.
This thing drives me crazy, it's like saying you're a bingo or lottery professional. You simply can't, when luck is involved in the game.
