In order to achieve success or make progress, one must be willing to endure some level of discomfort or hardship. In martial arts, this often means pushing through physical challenges, such as sore muscles or fatigue, in order to improve strength, endurance, and skill. However, it is important to balance this drive for improvement with self-care and injury prevention, as excessive or improper training can lead to serious harm. Ultimately, the key to success lies in finding a sustainable and balanced approach to training that challenges and motivates while also prioritizing safety and well-being.
