just before you sit in your seat and start studying every day, if you feel that you are not energetic enough or your brain is not clear enough, use various methods to generate strength. For example, use "deep breathing", "high-intensity exercise", "meditation" and "listening to Cang Gang music" to generate strength. Once the force is generated, you can learn with energy, clear mind, durability, toughness and ease and pleasure under the "force-driven".
Then, in the process of learning, always or when you feel weak, you can use methods such as "generating vigor", "generating self-confidence" and "accumulating learning experience" to "regenerate" or maintain strong strength. In this way, you can always be energetic, clear-headed, durable and strong.
