If you want to achieve peace of mind, you should learn to cultivate your moral character. For example, learn more calligraphy, painting, etc. For another example, practicing yoga more often can cultivate a peaceful mind. At the same time, we must stay away from those noisy lives without being affected.
Just like when I was in high school, I was particularly prone to irritability because of too much study pressure. So whenever I feel particularly anxious, I will choose to take out my copybook and practice my calligraphy all the time. This can not only improve your writing style, but also make your fonts more beautiful. At the same time, it can also calm your mind and stay away from external disturbances.
If I have more time, I will choose to maintain my inner peace through painting. Because once I start painting, I can easily calm down and keep immersed in painting. Whenever I finish a painting, I feel a special sense of accomplishment.
I have a friend who likes to practice yoga. And I found that the biggest benefit of yoga to her is that it can cultivate her body and mind. Yoga is an exercise that is good for her health. At the same time, when practicing yoga, the movements are very slow, which requires a certain amount of patience. Over time, you will develop a state of calm mind.
