"Creo que he mejorado desde el año pasado. Siempre estoy tratando de mejorar mi juego y mi temporada."

Simplified Meaning:

This quote means that the person feels they have become better than they were before. They are always working hard to improve and get better at what they do. Imagine a student in school; last year they struggled with math, but they studied more, asked the teacher for help, and practiced a lot. Now, they are doing much better with their math problems. Just like this student, the person in the quote is working hard to get better at their game, which could be a sport or any skill they are passionate about. They don’t stop trying even when they improve a bit because they always want to keep getting better. This way of thinking can help anyone trying to get better at something; by continually practicing and aiming to improve, they can achieve their goals and get good results. So, whether it’s learning a new language, playing an instrument, or even being better at a job, consistently putting in effort and trying to improve will help one succeed.
