Every sport is a mind game, and the mind aspect will always be superior; because it holds the power and has a role to play in every other aspect that is involved in the game.
Let's take E-sports and the FPS genre for example, players are given access to a weapon, which they think they'll only need to point and shoot; yes, that isn't wrong, and it would work half of the time. But when a player levels up by a certain level and masters a certain skill, so does someone else; hence, the competition gets tougher too, and as we learn new sills and tactics, our the skill ceiling keeps climbing a certain ladder. And when the skill ceiling is high enough, our brain/mind has more work to do, a lot multitasking gets involved.
Suddenly your aim game alone isn't helping much, not much of a benefit from using the average movement either; you might win a fight or two early game, but in order to win, you have to position yourself well, think before engaging in a fight and be aware of your surroundings and the ground you're holding.
A player who is capable of keeping all of this in mind, the one who processes every detail the fastest, usually ends up being victorious. These are the traits that gives a player the G.O.A.T status.
You got it right. From esports to sports, competition is at the thickest in the highest level. the only edge you can get is up in your mind.
So yeah, practice a lot till it becomes your habit, and till you've mastered everything else so you can do the brain work with all that time.
legit, that's really the way, the only way, achieving flow state.
