Carlos Alcaraz shared after the defeat at the Miami Open that he felt his opponents often played with an "unimaginable" form when they met him and if they had maintained that level, they would have had a much higher ranking. It sounds a bit confusing why it is like this, but it is actually a very familiar psychological aspect. When you start to get better, the world around you will change the way you approach it.
Alcaraz's opponents entered the field with a mentality of having nothing left to lose. Not being pressured to win, they are allowed to play more freely, daring to take "daredevil" shots that they may not choose in other circumstances. That freedom helps them reach higher limits than usual. Of course, they also learn very quickly from those matches.
Meeting someone better is always the most direct and effective way to learn, in any field. Every ball, every rhythm, every decision, every word, every experience, every experience are living data. When the psychology of acceptance is wide open, people's ability to absorb and adjust becomes more flexible. Alcaraz grew up in that way. He observed, experimented, and then shaped himself through confrontations with monuments.
But when you are better, when you are in the Top, the problem changes. You don't have many people to "look up to". At this point, learning no longer comes from the superiority of others, but focuses on how others try to defeat you.
This is a point that anyone will have to face in work and life. The world is not standing still to watch you alone move forward. The world moves faster than you think. Therefore, learning from someone better is not a fixed concept. It changes according to your own position, changes according to how you want to develop.
To constantly improve, you are not allowed to be trapped in a position in the ladder of knowledge or professional skills. At some point, you realize that you are not looking up to learn anymore, but focusing on standing firm, observing, adjusting. Otherwise, the previous success will become a limit.
